Optical structures with linear periodic properties (Bragg gratings, photonic crystals, waveguide arrays) exhibit a richness of phenomena in the nonlinear regime. In quadratic materials also nonlinear susceptibility can be engineered in periodic fashion through quasi-phase-matching (QPM) techniques.

Abstract
Optical structures with linear periodic properties (Bragg gratings, photonic crystals, waveguide arrays) exhibit a richness of phenomena in the nonlinear regime. In quadratic materials also nonlinear susceptibility can be engineered in periodic fashion through quasi-phase-matching (QPM) techniques.File in questo prodotto:
