Abstract:
1. An arrayed waveguide grating optical multiplexer/demultiplexer comprising: a substrate; and an arrayed waveguide grating formed on said substrate, having wherein said first input/output waveguide connected to the end facet of said one slab waveguide is disposed between the second input/output waveguide-group connected to the end facet of said one slab waveguide and a position where lights are output whose diffracted order are different from lights which are divided into every wavelength and coupled to each waveguide of the second input/output waveguide-group connected to the end facet of said one slab waveguide, in the case of which lights input from the first input/output waveguide connected to the end facet of said other slab waveguide are output from the second input/output waveguide-group connected to the end facet of said one slab waveguide, and said first input/output waveguide connected to the end facet of said other slab waveguide is disposed between the second input/output waveguide-group connected to the end facet of said other slab waveguide and a position where lights are output whose diffracted order are different from lights which are divided into every wavelength and coupled to each waveguide of the second input/output waveguide-group connected to the end facet of said other slab waveguide, in the case of which lights input from the first input/output waveguide connected to the end facet of said one slab wave guide are output from the second input/output waveguide-group connected to the end facet of said other slab waveguide.
