Integrated Optical Circulators and Isolators on a Ultra- Low-Loss Silicon Nitride Platform

Abstract: We show our progress on ring-based optical isolators and circulators, designed on both silica and silicon based photonic integration platforms. Isolation levels of better than-20 dB have been shown theoretically and-9 dB experimentally. OCIS codes: (230.3240) Isolators; (160.3820) Magneto-optical materials 1
