Design of a waveguide-type optical isolator using the Faraday and Cotton-Mouton effects for nonreciprocal and reciprocal mode conversions, respectively, is presented. A noteworthy conclusion is obtained that, comparing with the previous design using a phase-matched waveguide, the device length is reduced by allowing phase-mismatch between TE and TM modes in the waveguide.
