摘要： A polarization-independent wavelength demultiplexing apparatus for demultiplexing a light beam of at least one predetermined wavelength, includes a first demultiplexer for demultiplexing the light beam at a predetermined wavelength to obtain a component of the light beam in a first polarization state and second demultiplexer for demultiplexing the light beam at the predetermined wavelength to obtain a component of the light beam in a second polarization state, different from the first polarization state. The first demultiplexer and the second demultiplexer are arranged in a serial manner or in a parallel manner with respect to light transmitted through the demultiplexing structure.

摘要： A first light waveguide is formed, and second and third light waveguides are respectively connected to the first light waveguide at first and second positions. A first coupler for effecting tight branching and/or combining is arranged near the first position, and a second coupler for effecting light branching and/or combining is arranged near the second position. An optical amplifier is arranged on the first light waveguide between the first and second positions for compensating for a light loss of a light wave caused by each of the first and second coupler.

摘要： An optical device includes a channel or three-dimensional light waveguide for propagating a light wave therethrough and an optical coupler for effecting at least one of branching and combining of the light wave by splitting a wavefront of a field distribution of the light wave. The coupler is produced by forming a portion whose reflection factor is different from the waveguide, extending in a vertical direction of the waveguide. The portion of different reflection factor is formed deep enough in the vertical direction to perform the splitting of the wavefront of the field distribution of the light wave with respect to at least a horizontal or lateral direction, or the portion of different reflection factor is formed at a flat portion of the waveguide.
