Nonlinear Optical Gratings

Chapter
Part of the Springer Theses book series (Springer Theses)

Abstract

This chapter presents the results obtained on recording nonlinear gratings in azopolymers. It should be recalled that a nonlinear grating is a system, a polymer film in our case, in which the polar orientation induced by an electric field has a spatial modulation, resulting in a modulation of the nonlinear susceptibility tensor. When a light beam hits a diffraction grating, a redistribution of the intensity of the transmitted light is observed, a sequence of diffraction maxima in increasing order (±1, ±2, …) appearing on both sides of the propagation direction of the incident beam (which determines the direction of the 0 order) as we move away from the incident direction.
