Abstract

We summarise the scientific and technological aspects of the SAGAS (Search for Anomalous Gravitation using Atomic Sensors) project, submitted to ESA in June 2007 in response to the Cosmic Vision 2015-2025 call for proposals. The proposed mission aims at flying highly sensitive atomic sensors (optical clock, cold atom accelerometer, optical link) on a Solar System escape trajectory in the 2020 to 2030 time-frame. SAGAS has numerous science objectives in fundamental physics and Solar System science, for example numerous tests of general relativity and the exploration of the Kuiper belt. The combination of highly sensitive atomic sensors and of the laser link well adapted for large distances will allow measurements with unprecedented accuracy and on scales never reached before. We present the proposed mission in some detail, with particular emphasis on the science goals and associated measurements., Comment: 39 pages. Submitted in abridged version to Experimental Astronomy

2. A comparison between matter wave and light wave interferometers for the detection of gravitational waves

Author

Subjects
General Relativity and Quantum Cosmology
Abstract

We calculate and compare the response of light wave interferometers and matter wave interferometers to gravitational waves. We find that metric matter wave interferometers will not challenge kilometric light wave interferometers such as Virgo or LIGO, but could be a good candidate for the detection of very low frequency gravitational waves.

3. The 'Forgotten' Process : the emission stimulated by matter waves

Author

Tourrenc, Philippe, Angonin, Marie-Christine, and Wolf, Peter

Subjects
Quantum Physics
Abstract

In a famous paper where he introduces the A and B coefficients, Einstein considered that atomic decays of excited atoms can be stimulated by light waves. Here we consider that atomic decays can also be stimulated by atomic waves. It is however necessary to change the Maxwell-Boltzmann statistics of thermal equilibrium into Bose-Einstein statistics and to introduce a coefficient C which complements the list of the coefficients introduced by Einstein. Stimulated emission of light can be considered as the first step towards the laser. Similarly, stimulated production of matter waves can be considered as the basic phenomenon for an atom-laser. Most of the results that we obtain here are not new. However, the method that we use remains very close to elementary classical physics and emphasizes the symmetry between electromagnetic and matter waves from various points of view., Comment: submitted in European Journal of Physics

4. Tidal gravitational effects in a satellite

Author

Subjects
General Relativity and Quantum Cosmology
Abstract

Atomic wave interferometers are tied to a telescope pointing towards a faraway star in a nearly free falling satellite. Such a device is sensitive to the acceleration and the rotation relatively to the local inertial frame and to the tidal gravitational effects too. We calculate the rotation of the telescope due to the aberration and the deflection of the light in the gravitational field of a central mass (the Earth and Jupiter). Within the framework of a general parametrized description of the problem, we discuss the contributions which must be taken into account in order to observe the Lense-Thirring effect. Using a geometrical model, we consider some perturbations to the idealized device and we calculate the corresponding effect on the periodic components of the signal. Some improvements in the knowledge of the gravitational field are still necessary as well as an increase of the experimental capabilities; however our conclusions support a reasonable optimism for the future. Finally we put forward the necessity of a more complete, realistic and powerful model in order to obtain a definitive conclusion on the feasibility of the experiment as far as the observation of the Lense-Thirring effect is involved., Comment: accepted to General Relativity and Gravitation

5. Increase of the Number of Detectable Gravitational Waves Signals due to Gravitational Lensing

Author

Subjects
General Relativity and Quantum Cosmology, Astrophysics
Abstract

This article deals with the gravitational lensing (GL) of gravitational waves (GW). We compute the increase in the number of detected GW events due to GL. First, we check that geometrical optics is valid for the GW frequency range on which Earth-based detectors are sensitive, and that this is also partially true for what concerns the future space-based interferometer LISA. To infer this result, both the diffraction parameter and a cut-off frequency are computed. Then, the variation in the number of GW signals is estimated in the general case, and applied to some lens models: point mass lens and singular isothermal sphere (SIS profile). An estimation of the magnification factor has also been done for the softened isothermal sphere and for the King profile. The results appear to be strongly model-dependent, but in all cases the increase in the number of detected GW signals is negligible. The use of time delays among images is also investigated., Comment: Accepted for publication in General Relativity and Gravitation

Abstract

We consider a nearly free falling Earth satellite where atomic wave interferometers are tied to a telescope pointing towards a faraway star. They measure the acceleration and the rotation relatively to the local inertial frame. We calculate the rotation of the telescope due to the aberrations and the deflection of the light in the gravitational field of the Earth. We show that the deflection due to the quadrupolar momentum of the gravity is not negligible if one wants to observe the Lense-Thirring effect of the Earth. We consider some perturbation to the ideal device and we discuss the orders of magnitude of the phase shifts due to the residual tidal gravitational field in the satellite and we exhibit the terms which must be taken into account to calculate and interpret the full signal. Within the framework of a geometric model, we calculate the various periodic components of the signal which must be analyzed to detect the Lense-Tirring effect. We discuss the results which support a reasonable optimism. As a conclusion we put forward the necessity of a more complete, realistic and powerful model in order to obtain a final conclusion on the theoretical feasibility of the experiment as far as the observation of the Lense-Thirring effect is involved., Comment: Accepted in GRG (vol 36, Feb 2004)

Abstract

The VIRGO Central Interferometer (CITF) is a short suspended interferometer operated with the central area elements of the VIRGO detector. The main motivation behind the CITF is to allow the integration and debugging of a large part of the subsystems of VIRGO while the construction of the long arms of the antenna is being completed. This will permit a faster commissioning of the full-size antenna. In fact, almost all the main components of the CITF, with the exception of the large mirrors and a few other details, are the same as those to be used for the full-size detector. In this paper the present status of the VIRGO CITF is reported.

Abstract

This paper reports on recent results on passively mode-locked InAs/InP quantum-dot-based lasers. These low-dimensional structures have proved very attractive in improving most of the properties of these devices. Subpicosecond pulse generation at repetition rates up to beyond 300 GHz has readily been demonstrated. Ultranarrow RF linewidths reach record values of less than 1 kHz. Controlled optical feedback allows a further reduction of this linewidth yielding extremely low timing jitter. A comparison of single-section and standard two-section lasers is given for the first time. These performances open the way to various applications at 1.55 μm, including very high bit rate all-optical signal processing, frequency comb generation, radio over fiber, and low-noise all-optical oscillators.

Abstract

We report on electrical noise measurements on both Hg/sub 0.7/Cd/sub 0.3/Te test patterns and hybrid 320 /spl times/ 256 focal plane array in order to explain the low-frequency pixel flickering physical origin. Dark and under infrared illumination test patterns characterization highlights that the detector chip is not responsible for the flickering phenomenon. Taking into account the silicon readout chip influence when the full infrared complementary metal-oxyd semiconductor (IRCMOS) infrared detector is investigated, the indium bump based interconnecting system is finally pointed out as a potential excess noise source.

Abstract

International audience; Linewidth determination by self-heterodyne or self-homodyne methods may lead to mistaken interpretation, because these measurements often include significant broadening due to low-frequency FM noise. The effects of FM noise on these linewidth measurement schemes are investigated. An analytical formulation of the photocurrent autocorrelation function is given for different frequency noise signatures, the lineshape being extracted from numerical implementation. We apply these results to linewidth prediction for 850-nm commercial vertical-cavity surface-emitting lasers and get almost perfect agreement between the theoretical and the experimental approaches.

Abstract

The frequency noise of a laser has a direct influence on the lineshape and the linewidth. We present here the frequency-noise spectrum we obtained with selectively-oxidized Vertical-Cavity Surface-Emitting Lasers (VCSELs) emitting in the range of 850nm. We noticed different parts in the spectrum: a 1/fn part in the low-frequency range, independent of the output power, and a white-noise part in the high-frequency range, inversely dependent of the output power. The link with the laser lineshape is theoretically performed.

Abstract

The automatic control of the suspended mirrors is a major task in operating an interferometric gravitational wave antenna. To reach the extreme sensitivity required for this kind of detector, an accurate alignment and a stable locking of the interferometer on its working point are crucial. The solution of this problem is particularly complex in the case of a multistage pendulum, such as the suspension system for seismic isolation adopted in VIRGO. A precise knowledge of the suspension mechanical transfer functions (TFs) for different forces applied in the control servo-loops represents essential information to reach the goal. In this article, we describe the apparatus we developed to measure the VIRGO suspension TF and we report the results thus obtained on full-scale suspensions at the VIRGO site. Preliminary results for the implemented control system of the last suspension stage are also presented.

Abstract

We report linewidth and lineshape measurements on 1.55-/spl mu/m distributed Bragg reflector tunable laser diodes using the heterodyne method. We measure Lorentzian linewidths ranging from 3.5 to 25 MHz without any passive section injection. Biasing the Bragg section enhances the residual linewidth up to 6.2 MHz, changes the linewidth-power product, and brings an additional Gaussian lineshape. The feedback sensitivity of the overall setup is also demonstrated.

Abstract

We analyze the Michelson type experiment performed by Brillet and Hall. The order of magnitude of the gravitational effect (a beating frequency between two lasers) is calculated. We prove that Newtonian tidal forces could be observed when they originate from the oblateness of the Earth, from its rotation, from local masses, from the Moon or the Sun but not from the Galaxy (contrary to what has been recently claimed). We conclude that it is important to build a new parametrized theoretical framework for the analysis of high-precision experiments.

Abstract

International audience; In response to ESA's Call for proposals of 5 March 2007 of the COSMIC VISION 2015-2025 plan of the ESA science programme, we propose a M-class satellite mission to test of the Equivalence Principle in the quantum domain by investigating the extended free fall of matter waves instead of macroscopic bodies as in the case of GAUGE, MICROSCOPE or STEP. The satellite, called Matter Wave Explorer of Gravity, will carry an experiment to test gravity, namely the measurement of the equal rate of free fall with various isotopes of distinct atomic species with precision cold atom interferometry in the vicinity of the earth. This will allow for a first quantum test the Equivalence Principle with spin polarised particles and with pure fermionic and bosonic atomic ensembles. Due to the space conditions, the free fall of Rubidium and Potassium isotopes will be compared with a maximum accelerational sensitivity of 5*10 − 16 m/s2 corresponding to an accuracy of the test of the Equivalence Principle of 1 part in 1016. Besides the primary scientific goal, the quantum test of the Equivalence Principle, the mission can be extended to provide additional information about the gravitational field of the earth or for testing theories of fundamental processes of decoherence which are investigated by various theory groups in the context of quantum gravity phenomenology. In this proposal we present in detail the mission objectives and the technical aspects of the proposed mission.

Abstract

We report for the first time on the systematic measurement of timing jitter of 40-GHz self-pulsating Fabry-Perot laser based on InAs/InP quantum dashes emitting at 1.55 microm. Two different methods, one based on optical cross-correlation and one on electrical spectrum sideband integration are used and show a good agreement, yielding a jitter of 0.86 ps in the 1 MHz---20 MHz frequency range with a potential of 280 fs for optimized driving conditions. Amplitude noise and high-frequency timing jitter contributions are also discussed.

We report on electrical noise measurements on both Hg0.7Cd0.3Te test patterns and hybrid 320 × 256 focal plane array in order to explain the low frequency pixel flickering physical origin. Dark and under infrared illumination test patterns characterization highlights that the detector chip isn’t responsible for the flickering phenomenon. Taking into account the silicon readout chip influence when the full IRCMOS infrared detector is investigated, the indium bump based interconnecting system is finally pointed out as a potential excess noise source.

These measurements are compared with a comprehensive electrical model based on rate equation formalism. Taking into account diffusion phenomenon and structural parameters, we obtain a complete agreement between the model and the measurements above threshold and a quite similar tendency below threshold. The influence of Bragg section bias is also discussed.

Abstract

Medium frequency (100kHz - 1MHz) measurements of electrical noise power spectrum densitiy in DBR tunable lasers show particular behaviour around threshold, compared to classical edge-emitting structures. In this paper, we consider structures in which tunability is made by current injection. Standard monomode (SMSR > 40 DB) non tunable DBR lasers Noise Level follow a global shot-noise tendancy, except around the laser threshold current level (called Ith). In these structures, a strong excess of noise is classically established at Ith. Next, at Ith+epsilon, the noise level goes down again to the shot noise level. In DBR tunable lasers, this behaviour is exactly the same, except that epsilon grows up when the current level in the Bragg section gets stronger. The aim of this paper is to establish a link between the 'epsilon' factor and the current level in the Bragg section.

Abstract

The VIRGO suspensions are chains of passive mechanical filters designed to isolate the interferometer mirrors from seismic noise starting from a few Hz. In order to reduce the low-frequency swing of the mirror along the beam, an active control system, acting at the level of the suspension point, damps the main resonant modes of the system (all below 2.5 Hz). Another control loop, at the level of the optical payload, makes use of a digital camera monitoring the mirror position in all six degrees of freedom. Its main goal is to decrease the rms angular displacements of the mirror, on a time scale of several minutes, down to less than 1 μrad. All the seven suspensions of the VIRGO central interferometer are presently in operation, while the assembly of the last two, for the terminal mirrors, is in progress. The design and performance of the system are described in this paper. PACS number: 0480N (Some figures in this article are in colour only in the electronic version)

Systematic investigation of the performances of two-section MLLs emitting at 1.54 microm evidenced pulse width of 860 fs at 21.31 GHz repetition rate, peak power of approximately 500 mW and a time-bandwith product of 0.57. A 30 kHz linewidth of the photodetected radio-frequency electrical spectrum is further demonstrated at 21 GHz which is, to our knowledge, the lowest value ever reported for a quantum well device.

39. Tidal Gravitational Effects in a Satellite

Author

Tourrenc, Ph., Angonin, M.-C., and Ovido, X.

Abstract

Atomic wave interferometers are tied to a telescope pointing towards a faraway star in a nearly free falling satellite. Such a device is sensitive to the acceleration and the rotation relatively to the local inertial frame and to the tidal gravitational effects too. We calculate the rotation of the telescope due to the aberration and the deflection of the light in the gravitational field of a central mass (the Earth and Jupiter). Within the framework of a general parametrized description of the problem, we discuss the contributions which must be taken into account in order to observe the Lense-Thirring effect. Using a geometrical model, we consider some perturbations to the idealized device and we calculate the corresponding effect on the periodic components of the signal. Some improvements in the knowledge of the gravitational field are still necessary as well as an increase of the experimental capabilities; however our conclusions support a reasonable optimism for the future. Finally we put forward the necessity of a more complete, realistic and powerful model in order to obtain a definitive conclusion on the feasibility of the experiment as far as the observation of the Lense-Thirring effect is involved.

41. Changement de phase dans un champ de gravitation: Possibilité de détection interférentielle

Author

B. Linet and P. Tourrenc

Subjects
Gravitation, Physics, Disturbance (geology), Classical mechanics, General Physics and Astronomy, Wave function, Electromagnetic radiation, Eikonal approximation
Abstract

We calculate the phase shift of a quantum mechanics wave function and of an electromagnetic wave produced by any gravitational disturbance using the eikonal approximation. We examine the best conditions for detection of gravitational waves. In particular, we establish that any resonant effect has a linear time dependance.

Electromagnetic field, Physics, Gravitation, Field electron emission, Superposition principle, Quantization (physics), Classical mechanics, Parallel transport, General relativity, Field representation
Abstract

The concept of parallel transport is generalized. It leads to a geometric structure of charged fields. A quantization principle of charge is put forward and the Aharonov-Bohm effect is interpreted within the framework of a one-valued field representation and superposition principle. No explicit equation is demanded to describe the electron field: The interpretation is a pure geometric one.

Subjects
Physics, Classical mechanics, Orders of magnitude (time), Quantum electrodynamics, Resonance, First order, Electromagnetic radiation
Abstract

Some phenomena of resonance between a gravitationnal wave and an electromagnetic radiation contained in a cavity are studied; the use of a simplified pattern allows to follow calculations to their end and to pick out orders of magnitude. The whole of this study is done by means of a perturbative method restricted to first order, within Einstein-Maxwell’s theory.

Subjects
Electromagnetic field, Physics, Physics and Astronomy (miscellaneous), Gravitational field, Gravitational wave, Electromagnetic cavity, Quantum electrodynamics, Gravitational acceleration, Electromagnetic radiation, Magnetic radiation reaction force, Gravitational redshift
Abstract

Gravitational radiation is considered within the first-order approximation. A pattern of an electromagnetic cavity is studied: Gravitational waves give rise to a deformation of the planes limiting the cavity. This deformation alters the electromagnetic radiation. Several cases are studied and orders of magnitude are put forward.

46. A preliminary discussion of Dulkyn interferometer

Author

Tourrenc, Ph. and Balakin, A. B.

Abstract

The Dulkyn interferometer in Kazan is an active ring laser where the light propagates along two different paths. It has been developed with the idea that it could detect low frequency gravitational waves on Earth. Considering Dulkyn as a detector of periodic strains of order of h~ 10−22at low frequencies (10−3Hz−10−5Hz) we calculate that 30 W is the order of magnitude of the optical power necessary to beat the photon noise in the case of a long observation time (T= 4 months) and a reasonable signal to noise ratio (r= 3). We estimate that the displacement noise of the mirrors must not exceed 5×10−19m/$\sqrt{{Hz}}$. Dulkyn is also sensitive to accelerations and rotations. The acceleration noise does not seem to be troublesome ($\widetilde{g}\lesssim 0.1{m} {s}^{-2}/\sqrt{{Hz}}$), but the angular velocity noise must be less than 5×10−11s−1/$\sqrt{{Hz}}$. The maximum strain (10−22) is obtained with free (pendulous) mirrors. Out of resonance, the strain is many orders of magnitude smaller when the mirrors are fixed on a rigid support. Such a case would rule out the possibility of a detection. As a conclusion we emphasize that the Dulkyn design does not bring any decisive improvement for the detection of low frequency gravitational waves on Earth.

Abstract

We summarise the scientific and technological aspects of the SAGAS (Search for Anomalous Gravitation using Atomic Sensors) project, submitted to ESA in June 2007 in response to the Cosmic Vision 2015-2025 call for proposals. The proposed mission aims at flying highly sensitive atomic sensors (optical clock, cold atom accelerometer, optical link) on a Solar System escape trajectory in the 2020 to 2030 timeframe. SAGAS has numerous science objectives in fundamental physics and Solar System science, for example numerous tests of general relativity and the exploration of the Kuiper belt. The combination of highly sensitive atomic sensors and of the laser link well adapted for large distances will allow measurements with unprecedented accuracy and on scales never reached before. We present the proposed mission in some detail, with particular emphasis on the science goals and associated measurements., Physics

49. Bragg section effects on linewidth and lineshape in 1.55-μm DBR tunable laser diodes.

Abstract

We report linewidth and lineshape measurements on 1.55-μm distributed Bragg reflector tunable laser diodes using the heterodyne method. We measure Lorentzian linewidths ranging from 3.5 to 25 MHz without any passive section injection. Biasing the Bragg section enhances the residual linewidth up to 6.2 MHz, changes the linewidth-power product, and brings an additional Gaussian lineshape. The feedback sensitivity of the overall setup is also demonstrated. [ABSTRACT FROM PUBLISHER]
