Abstract

Monolithic optical integrated circuits are key components for future optical communications as well as optical signal processing systems.¹ Up to the present, various structures have been proposed for the integration of optical devices. However, crystal growth and process technology for fabrication is so complicated that only a few reports on the fabrication have been published. Furthermore, key devices for integration, such as small-sized optical switches, have not yet been developed.
