Abstract

Introducing a chirping structure into a periodic nonlinear optical (NLO) susceptibility (chi) ⁽²) in a slad-waveguide, enhanced second-harmonic generation (SHG) has been preliminarily demonstrated in the Cerenkov-radiative scheme. Since this chirped periodic (chi) ⁽²) structure can be general form to both uniform and periodic (chi) ⁽²) cases, the available Cerenkovian SHG powers are compared for three different NLO (chi) ⁽²) structures such as the uniform, periodic and chirped periodic schemes, based on the theoretical model of the chirped (chi) ⁽²) configuration. Some of experimental verification on the enhanced SHG power is also given with vinylidene cyanide/vinyl acetate organic copolymer in an asymmetric slab-waveguide.
