    摘要： A diffraction grating is disposed adjacent to a ridge waveguide formed on a substrate (cladding). Assumed that a light propagation direction at the waveguide is z, a direction of width of the waveguide is x, and ends of the diffraction grating of this embodiment is x=gmin when z=0 and x=gmax when z=L/2, the ends of the diffraction grating can be expressed as the following functions f(z). Namely, f(Z)=gmin+(gmax−gmin)×(2z/L)n when 0≦z≦L/2, and f(Z)=gmin+(gmax−gmin)×(2-2z/L)n when L/2≦z≦L, where n>1.

    摘要： An optical add/drop multiplexer device which is capable of extracting or inserting optical signals of arbitrary wavelength and having a wavelength selection characteristic with a narrow bandwidth, and which is compact in size and highly reliable. The device is formed by a substrate member; a plurality of optical waveguides, formed over the substrate member in layers with a prescribed interval along a direction perpendicular to a plane of the substrate member, each optical waveguide having a portion arranged in parallel and in proximity to an adjacent optical waveguide to form a coupling section; and a diffraction grating member, provided at the coupling section and having a prescribed period along a light propagation direction, for reflecting light signals with a specific wavelength among light signals entered from one of adjacent optical waveguides to another one of the adjacent optical waveguides.
