An optical device that can be made to switch either passively or                actively like an electronic transistor at optical frequencies can find          important use in numerous engineering systems, particularly                     communications and computing systems.  The purpose of this                      investigation is to further develop the understanding through both              experimental and theoretical research of optical power-dependent                phenomena in optical waveguides.  These waveguides include dielectric           waveguides, semiconductor surfaces, and thin metal films. A primitive           bistable device has already been demonstrated.  Both theoretical and            experimental research involving more elaborate systems will be                  performed.  Several device configurations involving controlled                  bistability, designing and testing nonlinear directional couplers, and          phase conjugation and four-wave mixers will be examined.
