Multicolor Talbot effect and control of polychromatic light patterns in modulated photonic lattices

Abstract

We analyze propagation of polychromatic light patterns in modulated photonic lattices created with arrays of periodically curved coupled optical waveguides. We demonstrate that in waveguide arrays with specially designed modulation periodic recurrences of input light patterns produced by white-light and supercontinuum sources can be realized, e.g., through multicolor Talbot effect.
