Self-contained integrated bistable optical devices

Abstract

We have built self-contained bistable optical devices using integrated Fabry-Perot resonators formed by attaching dielectric mirrors to the cleaved ends of a LiNbO3 substrate containing a Ti in-diffused waveguide modulator. Feedback from a novel composite photovoltaic detector which samples the output beam is applied to the modulator electrodes. We also describe an off-axis extraordinary wave resonator which permits low-energy operation. These integrated bistable devices operate solely with optical inputs and outputs; no source of electrical energy is required.
