Shaping and switching of polychromatic light in arrays of periodically curved nonlinear waveguides

Abstract

Abstract:We overview our recent theoretical results on spatio-spectral control, diffraction management, and broadband all-optical switching of polychromatic light in periodically curved one and two dimensional arrays of coupled optical waveguides. In particular, we show that polychromatic light beams and patterns produced by white-light and supercontinuum sources can experience wavelength-independent normal, anomalous, or zero diffraction in specially designed structures. We also demonstrate that in the nonlinear regime, it is possible to achieve broadband all-optical switching of polychromatic light in a directional waveguide coupler with special bending of the waveguide axes. Our results suggest novel opportunities for creation of all-optical logical gates and switches which can operate in a very broad frequency region, e.g., covering the entire visible spectrum. PACS

Collisions between discrete spatiotemporal dissipative Ginzburg-Landau solitons in two-dimensional photonic lattices

“…These surface solitons become possible solely due to discreteness effects and they exist in neither continuous nor linear limits. Some of the specific features of such discrete surface optical solitons in other relevant physical settings have been recently investigated both theoretically [20][21][22][23][24][25][26][27] and experimentally [28][29][30][31] (see also Ref. [32][33][34] for recent comprehensive overviews of experimental and theoretical developments in the area of discrete optical solitons).…”
