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.
