Optical isolator with magnetic garnet/semiconductor magneto-optic waveguide employing nonreciprocal radiation mode conversion

摘要

An integrated optical isolator with a semiconductor guiding layer can be constructed by wafer direct bonding technique, by which two wafers are connected without any adhesives. The optical isolator, employing a nonreciprocal guided-radiation mode conversion, with the semiconductor guiding layer is described. The isolator is composed of magneto-optic waveguides with magnetic garnet/GaInAsP/InP (or AllnAs-oxide) structure. Waveguide parameters of the magneto-optic waveguides are demonstrated to design the isolator.
