Abstract

Many studies have been devoted to the search of photonic and phononic band gaps, but relatively few works are dealing with the simultaneous control of phonons and photons. Phoxonic structures hold promises for the simultaneous confinement and tailoring of sound and light waves with potential applications to acousto-optical devices and highly controllable photon-phonon interactions. The aim of this presentation is to investigate both the photonic and photonic band structures, and in particular dual photonic-photonic band gaps, in a model of silicon strip waveguide in which each unit cell contains one hole in the middle and two symmetric stubs on the side of the waveguide. We use the finite-element (FE) methods to calculate the dispersion curves and the finite difference time domain (FDTD) to obtain the transmission spectra. Appropriate choices of the geometrical parameters allows us to obtain a complete phononic gap together with a photonic band gap of a given polarization and symmetry. Then, we investigate the possibility of confined modes inside cavities inserted in the phoxonic strip waveguide. Such situation is suitable to enhance the photon-phonon interaction. The optomechanical and photoelastic effects of a phononic/photonic cavity are discussed and analyzed on a two dimensional infinite phoxonic crystal before being applied to the strip waveguide. Depending on the choice of the phononic defect mode, the importance of the optomechanical and the photoelastic effects on the photonic mode is then discussed and compared. Finally, we discuss the actual values of the geometrical parameters, compatible with the technological fabrication constraints, in order to find the photonic features in the range of the telecommunication wavelengths, with the acoustic frequencies falling in the gigahertz regime.

Abstract

International audience; The last years have seen a significant rise in the number of studies of band gap materials for acoustic waves. Basically, these artificial materials can be classified into two distinct families: phononic crystals and acoustic metamaterials. Indeed, they can both prohibit the propagation of acoustic waves in certain frequency ranges for all directions of incidence, but the physical phenomena behind are markedly different. The key parameter to obtain band gaps in the case of phononic crystals is periodicity, while the local frequency resonance of each basic cell dominates in the case of acoustic metamaterial. Propagation of acoustic waves in phononic crystals has been reported for bulk, Lamb and surface acoustic waves. Most of the experimental studies focused on the attenuation involved within band gaps. The purpose of the present paper is to investigate the phase shift and the groupe delay induced by a periodic structure of pillars on a surface in a wide frequency range owning locally-resonant and Bragg band gaps. The experimental dispersion curves are presented accordingly and a very good agreement between theory and experiment is obtained.

Abstract

International audience; We demonstrate the existence of non-radiative complete surface acoustic wave(SAW)bandgaps for two-dimensional piezoelectric phononic crystals of holes. Holes of finite depth in a semi-infinite LiNbO3 substrate are specifically considered. SAWbandgaps are determined from the band structure calculated with a three-dimensional finite element method taking into account material anisotropy and piezoelectricity. The effect of hole geometry on the bandgaps has been investigated. It is further found that the complete band gap does not close for moderately conical holes.

Abstract

International audience; The influence of material loss on the complex band structure of two-dimensional phononic crystals is investigated. A viscoelasticity model is added to the extended plane-wave expansion (EPWE) method, with viscosity proportional to the frequency. It is found that losses have a stronger influence on the real than on the imaginary part of Bloch waves, in contrast with propagation in homogeneous media. Flat bands, i.e., bands initially showing low group velocity without losses, acquire an enhanced damping as compared to bands with larger group velocities. Losses are also found to limit the appearance of large group slownesses, or conversely small group velocities.

Abstract

International audience; Phononic crystals composed of lossy materials with viscosity constants proportional to the frequency are considered. Complex band structures are computed for such crystals using an extended plane wave expansion method. The effect of losses on both the real and the imaginary part of Bloch waves is investigated in the case of a two-dimensional square-lattice phononic crystal of holes in silicon. It is in particular found that losses limit the appearance of large group slownesses, or conversely small group velocities.

Abstract

We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell which include the simple square, triangular and honeycomb lattices as particular cases. We show that complete phononic and photonic band gaps can be obtained from the honeycomb lattice as well as BN lattices close to honeycomb. Otherwise, all investigated structures present the possibility of a complete phononic gap together with a photonic band gap of a given symmetry, odd or even, depending on the geometrical parameters.

Abstract

International audience; The simultaneous existence of photonic and phononic band gaps opens up many possibilities for enhancing acousto-optical interactions at a common wavelength scale. In this paper, we will give a brief review of the current state of the art dedicated to these structures, before focusing on theoretical investigations of the band diagrams of such 'phoxonic' crystals. We will more particularly focus on air/lithium niobate crystals in view of designing integrated phoxonic devices relying on surface acoustic waves. A comparison with a silicon based solution, in particular with slab structures, will also be drawn.

Abstract

International audience; Interface acoustic waves (IAWs) propagate along the boundary between two perfectly bonded solids. For a leakage-free IAW, all displacement fields must be evanescent along the normal to the boundary inside both solids, but leaky IAWs may also exist depending on the selected combination of materials. When at least one of the bonded solids is a piezoelectric material, the IAW can be excited by an interdigital transducer (IDT) located at the interface, provided one can fabricate the transducer and access the electrical contacts. We discuss here the fabrication and characterization of IAW resonators made by indirect bonding of lithium niobate onto silicon via an organic layer. In our fabrication process, IDTs are first patterned over the surface of a Y-cut lithium niobate wafer. A thin layer of SU-8 photo-resist is then spun over the IDTs and lithium ni-obate to a thickness below one micrometer. The SU-8-covered lithium niobate wafer then is bonded to a silicon wafer. The stack is subsequently cured and baked to enhance the acoustic properties of the interfacial resist. Measurements of resonators are presented, emphasizing the dependence of propagation losses on the resist properties. Comparison with theoretical computations based on periodic finite element/boundary element analysis allows for explanation of the actual operation of the device.

Experiments show that an enhancement factor of the elasto-optical interaction of the order of 61 is obtained thanks to slow light effects in the PhC. By means of FDTD-2D simulations, we propose a numerical estimation of the elasto-photonic interaction.

Abstract

We present the design of two waveguides (ladder and slot-ladder waveguides) implemented in a silicon honeycomb photonic-phononic crystal slab, which can support slow electromagnetic and elastic guided modes simultaneously. Interestingly, the photonic bandgap extends along the first Brillouin zone; so with an appropriate design, we can suppress propagation losses that arise coupling to radiative modes. From the phononic point of view, we explain the slow elastic wave effect by considering the waveguide as a chain of coupled acoustic resonators (coupled resonant acoustic waveguide), which provides the mechanism for slow elastic wave propagation. The ladder waveguide moreover supports guided phononic modes outside the phononic bandgap, similar to photonic slab modes, resulting in highly confined phononic modes propagating with low losses. Such waveguides could find important applications to the observation of optomechanical and electrostriction effects, as well as to enhanced stimulated Brillouin scattering and other opto-acoustical effects in nanoscale silicon structures. We also suggest that they can be the basis for a "perfect" photonic-phononic cavity in which damping by coupling to the surroundings is completely forbidden.

Abstract

[EN] The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator down to its ground state to the management of the speed of guided light pulses by exciting sound waves. A common feature of all these phenomena is the feasibility to tightly confine photons and phonons of similar wavelengths in a very small volume. Amongst the different structures that enable such confinement, optomechanical or phoxonic crystals, which are periodic structures displaying forbidden frequency band gaps for light and sound waves, have revealed themselves as the most appropriate candidates to host nanoscale structures where the light-sound interaction can be boosted. In this review, we describe the theoretical tools that allow the modeling of the interaction between photons and acoustic phonons in nanoscale structures, namely cavities and waveguides, with special emphasis in phoxonic crystal structures. First, we start by summarizing the different optomechanical or phoxonic crystal structures proposed so far and discuss their main advantages and limitations. Then, we describe the different mechanisms that make light interact with sound, and show how to treat them from a theoretical point of view. We then illustrate the different photon-phonon interaction processes with numerical simulations in realistic phoxonic cavities and waveguides. Finally, we introduce some possible applications which can take enormous benefit from the enhanced interaction between light and sound at the nanoscale.

Abstract

International audience; The objective of this presentation is to discuss potential applications of phononic crystals to the field of micro and nano-acoustics. Phononic crystals are two or three-dimensional periodically structured materials that show a number of amazing properties if properly designed. For instance, complete band gaps can be obtained, that is frequency ranges within which no wave propagation is allowed, whatever the incidence and the polarization. Even outside band gaps, the periodic structure leads to very strong spatial and temporal dispersion, resulting in properties unavailable with usual homogeneous materials. Confinement by defects (created by altering locally the otherwise perfectly periodic arrangement) has been shown to lead to efficient energy storage in cavities, to wave guiding in very narrow spaces, and more generally to simple phononic circuits. Some demonstrations of phononic crystals for surface acoustic waves have been published recently, though technologies for the micro and nano-structuration of piezoelectric materials still need to be improved (for instance to obtain deep holes of sub micron aperture at the surface). The spatial dispersion properties of finite phononic crystals have been employed to design acoustic lenses, through the use of positive or negative refraction. Recent achievements in the field will be highlighted, with a particular focus on acoustic waves in fluids. Topics include the confinement of waves in sub-wavelength channels, the potential design of phononic transducers and sensors, and the conversion of surface to bulk acoustic waves and vice versa.

Abstract

International audience; The objective of this invited paper is to present a review of the domain of phononics. A general aim is to attract new researchers to this growing field that has strong connections with ultrasonics, especially as far as applications are concerned. Along this talk, I will try and provide answers to a number of basic questions, such as: What is phononics, Who is presently involved in phononics? What is new and what is not? Why switch to phononics? What is still to be done? Are there any applications? Phononics can be defined as the science of designing artificial acoustic materials with tailored dispersion properties. Of special interest are phononic crystals, two- or three-dimensional periodically structured materials that show a number of amazing properties - but only if properly designed. For instance, strong confinement of wave energy can be obtained inside complete band gaps, i.e. frequency ranges within which no wave propagation is allowed, whatever the incidence and the polarization. Even outside band gaps, the periodic structure leads to very strong spatial dispersion, resulting in properties unavailable with usual homogeneous materials. The basic tool to understand these dispersion properties is derived from solid state physics. The so-called band structure summarizes the dispersion relations of all waves propagating in a phononic crystal. Some simple hints to understand band structures will be given. I will then highlight recent achievements in the field of phononics and use them to emphasize that much remains to be achieved. For instance, although the theory of band gaps is quite advanced, experimental demonstrations have not been that many, and technical difficulties still stand ahead. Confinement by defects (created by altering locally the otherwise perfectly periodic arrangement) has been shown to lead to efficient energy storage in cavities, to wave guiding in very narrow spaces, and more generally to simple phononic circuits; however, the practical achievement of true phononic circuits or filters is still an unsolved challenge. It is highly desirable to design phononic crystals for surface acoustic waves, and initial demonstrations have been performed, but there is still a major bottleneck to their development: efficient structural technologies for piezoelectric materials have to be obtained (for instance to obtain deep holes of sub micron aperture at the surface). The spatial dispersion properties of finite phononic crystals have been employed to design acoustic lenses, through the use of positive or negative refraction; but these lenses have shown limited efficiency, and limited frequency range (i.e. for short pulses). The geometrical dimensions of phononic crystals ultimately dictate the frequency ranges inside which band gaps appear. This relation is dependent on the acoustic velocities of the composing materials, but also on the boundary conditions imposed by the limits of the periodic parts of an actual sample. I will give a summary of achievements that have been obtained so far for bulk waves, surface waves, phononic plates, phononic layers-on-a-substrate, and true 3D phononic structures. It will be seen that the frequency range of operation has generally been limited in practice by available transducers for acoustic or elastic waves. As one possible answer to that, I will discuss the use of phononics to directly improve transducers or dramatically change their design.
