Abstract:
An arrayed waveguide grating optical multiplexer/demultiplexer, comprising:an input-side slab waveguide having diffraction grating and waveguide end faces; an output-side slab waveguide having diffraction grating and waveguide end faces; an array waveguide grating including a plurality of channel waveguides connecting the diffraction grating end face of the input-side slab waveguide to the diffraction grating end face of the output-side slab waveguide; at least one input waveguide connected to the waveguide end face of the input-side slab waveguide; and at least one output waveguide connected to a waveguide end face of the output-side slab waveguide, wherein a focal length of the diffraction grating end face of the output-side slab waveguide is longer than a focal length of the waveguide end face of the input-side slab waveguide.
