ABSTRACT:
An optical device includes a body of a semiconductor material having a waveguide therein along which light flows and means for providing gain to the light. A layer of an amorphous or polycrystalline metallic-ferromagnetic material extends along the waveguide and means, such as a permanent magnet, provides a magnetic field to the metallic-ferromagnetic material layer. This provides an optical isolator of the Faraday rotation type which can be integrated with a variety of material systems including those commonly used to fabricate semiconductor lasers, arrays and amplifiers.
