Paper Abstract

Space-division optical switches will be indispensable for future fiber-optic communication systems such as fiber-optic subscriber-line concentrators, photonic inter-module connectors, and protection switches. This paper reports recent progress on both silica-based thermo-optic optical switches with drive electronics. Two types of free-space switch modules are also reviewed; analog free-space switching modules which use liquid crystal beam shifters and digital free-space switching modules which incorporate semiconductor photonic switch array devices.
