Abstract

Abstract: We show that light evolution occurring in waveguide arrays with a particular n-functional square root dependence of coupling coefficients can be used to produce classical analogues of nonlinear quantum coherent states. Using operator algebras we obtain closed-form expressions describing the optical field dynamics in such structures. In addition, by numerically monitoring the Mandel''s parameter, we obtain the conditions necessary to generate sub-Poissonian and super-Poissonian classical intensity distributions in the proposed photonic lattices.

Abstract

We propose a versatile approach for generating multipartite W states in predesigned on-chip multiport photonic lattices. It is shown that is possible to produce photon-encoded W states where exactly one photon is coherently "shared" among N optical modes by judiciously adjusting the coupling coefficients involved in one-dimensional arrays of evanescently coupled single-mode waveguides. Two-dimensional waveguide configurations are also investigated as possible avenues to produce W states with equal probability amplitudes and equal relative phases. [ABSTRACT FROM AUTHOR]

3. Quantum state transformations by multiport array beam splitters.

Author

Perez-Leija, Armando, Keil, Robert, Moya-Cessa, Hector, Szameit, Alexander, and Christodoulides, Demetrios N.

Abstract

We introduce a multiport waveguide array beam-splitter that emulates the action of the angular momentum matrix Jx. Quantum transformations carried out by such devices are discussed and pertinent examples are provided. [ABSTRACT FROM PUBLISHER]

4. Observation of Bloch-like oscillations in Glauber-Fock oscillator lattices.

Author

Keil, Robert, Perez-Leija, Armando, Moya-Cessa, Hector, Szameit, Alexander, and Christodoulides, Demetrios N.

Abstract

We report the first observation of classical Bloch-like oscillations and revivals of light in a new class of dynamic optical systems-the so-called Glauber-Fock oscillator lattices. [ABSTRACT FROM PUBLISHER]
