Abstract
An optical circulator is a device that routes optical pulses from port to port in a predetermined manner, e.g. in a 3-port optical circulator, optical pulses entering portare routed out of port, while optical pulses entering portexit out of portand optical pulses fed into portexit out of port. Currently such an optical circulator is made of discrete components such as magnetooptic garnets, rare-earth magnets and optical polarizers that are packaged together with fiber optic elements. Disclosed herein is a different kind of optical circulator that is monolithically integrated on a single semiconductor substrate and that is applicable for the routing of optical pulses. The embodied invention will enable photonic integrated circuits to incorporate on-chip optical circulator functionality thereby allowing much more complex optical designs to be implemented monolithically.
