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.
