Propagation of nonclassical states of light through one-dimensional photonic lattices
B. M. Rodríguez-Lara
Abstract
We study the propagation of nonclassical light through arrays of coupled linear photonic waveguides and introduce some sets of refractive indices and coupling parameters that provide a closed-form propagator in terms of orthogonal polynomials. We present propagation examples of nonclassical states of light—single photon, coherent state, path-entangled state, and two-mode squeezed vacuum—impinging into two-waveguide couplers and a photonic lattice producing coherent transport.
