We analyze coherent anti-Stokes Raman scattering in thin-film dielectric waveguides. Extraordinarily large signal levels are predicted, and two applications of this phenomenon are discussed.

An experimental technique for calibrating the photobleaching process in a nonlinear optical material is presented. The technique depends on the existence of a sharp interface between the bleached and unbleached layers of the material which travels across the film but otherwise has a constant shape. The sharp interface of constant shape is a feature of a general model and is consistent with our experimental results. By determining the dependence of the velocity on the bleaching intensity, the order of the photobleaching kinetics is determined.

Novel difunctional nonlinear optical (NLO) azo compounds with exceptional thermal stability have been synthesized and incorporated into side-chain and cross-linked polymers. The nonlinear optical response of these polymers has been studied with second-harmonic generation and electrooptic measurements. Channel waveguide intensity modulators displayed an electrooptic coefficient of 13.1 pm/V.
