Technical Examples

An array waveguide diffraction grating optical multiplexer/demultiplexer having an input waveguide, an input side slab waveguide, an output side slab waveguide, an output waveguide, an array waveguide provided between the input side slab waveguide and output side slab waveguide having a length different sequentially between the adjacent waveguides, wherein the output waveguide is arranged so that the angle formed between each output waveguide and the normal line of the Rowland circle of the output waveguide is sequentially increased from the central output waveguide to the output waveguide at both ends of the central output waveguide, and asymmetry of the passband of the output waveguide based on the form of field distribution at a light collecting point of the output side slab waveguide is decreased.
