ABSTRACT:
An arrayed waveguide grating optical multiplexer/demultiplexer includes an arrayed waveguide grating formed on a substrate. The arrayed waveguide grating includes two slab waveguides, one arrayed waveguide, first input/output waveguides respectively connected to each end facet of slab waveguides, and second input/output waveguide-groups respectively connected to the end facets. The first input/output waveguides are provided for inputting or outputting a plurality of lights (λ1˜λn) each of which has a different wavelength and multiplexed. The second input/output waveguides are provided for individually inputting or outputting a plurality of lights (λ1˜λn). One arrayed waveguide23can be used to carry out simultaneously multiplexing and demultiplexing. It is able to carry out simultaneously multiplexing and demultiplexing with one arrayed waveguide grating.
