A nonreciprocal TE-TM mode converter with a semiconductor guiding layer was studied. The mode converter comprised a magnetic garnet/GaInAsP/InP (AlInAs-oxide, air) waveguide. When the lower cladding layer was air, the propagation distance required for a 45° mode conversion was estimated to be several hundreds of microns at 1.55 μm.
