    摘要: An optical wavelength multiplexer/demultiplexer includes a substrate, an input channel waveguide, an input slab waveguide, a channel waveguide array which has a plurality of channel waveguides, each channel waveguide differing in length from its neighboring waveguide by predetermined amount, an output slab waveguide, and a plurality of output channel waveguides. The input slab waveguide or output slab waveguide have a temperature compensation material, in its light path, having an opposite sign of diffraction temperature change to the plurality of channel wave guides, or a material capable of canceling a change in the in-phase plane of light having each wavelength which occurs in a vicinity of the channel waveguide array and the slab waveguide, or a waveguide for band width adjustment on which a waveguide to adjust band width of wavelength multiplexing light is provided.
