| Abstract(in English) | Optical waveguide isolators are important integrated optics components that protect optical active devices from unwanted reflection. Two optical isolators, employing nonreciprocal phase shifter and nonreciprocal guided-radiation mode conversion, with a semiconductor guiding layer are described. The former isolator needs long propagation distance for the nonreciprocal phase shift and the latter has few acceptable error range of the fabrication. Selective oxidation of AlInAs layer with low refractive index can enhance the magneto-optic effect and improve the characteristics. We successfully fabricated the optical waveguide with AlInAs-oxide under cladding layer and the refractive index of the AlInAs-oxide was estimated to be 2.45 at 1.55μm. |
