| 英文摘要 | An optical waveguide isolator for use in an optical communication system is disclosed. The optical waveguide isolator comprises a semiconductive light amplifier structure including an n-type semiconductor substrate (1) having a surface (1a) for layers to be formed thereon, a first n-type cladding layer (3) formed on the substrate, an active layer (4) formed on the first cladding layer, a p-type second cladding layer formed on the active layer, a first electrode (9) formed on the surface of the semiconductor substrate opposite to the layer-forming surface, and a second electrode (8) formed on the second cladding layer; the first and the second cladding layers and the active layer form an optical waveguide in which the light wave propagates. The semiconductive light isolator structure further comprises a light absorptive magnetic material layer (8a), e.g. of nickel, having a light absorption function for the light wave propagating through the optical waveguide. The magnetic material layer is magnetized so as to have a magnetic-field component in the direction which corresponds to the magnetic vector of the light wave. |
