Abstract

Integrated optics waveguides are ideal media for nonlinear optical interactions because high power densities can be maintained over centimeter propagation distances. Recent work in our laboratory, as well as that of other workers in the field will be reviewed. Liquid crystal media placed on top of thin films provide simple nonlinear waveguides in which optical bistability, all-optical switching and the modulation of one light beam by a another have all been demonstrated for different materials and different polarization conditions. The optical tuning of surface gratings on InSb thin film waveguides will be described. Recent experiments on nonlinear coherent directional couplers will be reviewed. If time permits, new materials for nonlinear integrated optics waveguides will be discussed, as well as new developments in the theory of nonlinear guided waves.
