Abstract
An all-optical integrated optics beam-scanning device is analyzed. It consists of a surface relief grating used to couple both a control and a signal beam into and out of a nonlinear planar waveguide, respectively. Varying the control beam power tunes the signal beam out-coupling angle. Both local and diffusive nonlinearities are considered, and various design parameters are discussed. The theoretical results are compared to experimental data from ZnS waveguides for the thermal diffusive case.
