Fabrication processes of a magneto-optic waveguide with a Si guiding layer for an optical isolator employing a nonreciprocal guided-radiation mode conversion are investigated. The optical isolator is constructed on a silicon-on-insulator (SOI) structure. The magneto-optic waveguide is fabricated by bonding the Si guiding layer with a cerium-substituted yttrium iron garnet (Ce:YIG). The relationship of waveguide geometric parameters is determined at a wavelength of 1550 nm. The results show that larger tolerance for isolator operation can be obtained at smaller gaps between Si and Ce:YIG. Bonding processes including photosensitive adhesive bonding and surface activated bonding are then compared. It is found that the surface activated bonding process is easier to control and more promising than the photosensitive adhesive bonding.

ABSTRACTDiluted magnetic semiconductor Cd1-xMnxTe was proposed as a magneto-optic material for waveguide optical isolator. Waveguide propagation loss below 1 dB/cm, complete magneto-optical mode conversion and optical isolation of 20 dB were demonstrated with Cd1-xMnxTe waveguides grown on GaAs substrate. The high isolation ratio, high magneto-optic effect and low propagation loss achieved in the magneto-optical waveguide grown on the semiconductor substrate shows the feasibility of monolithical integration of an optical isolator with semiconductor optoelectronic devices.
