A wavelength demultiplexer structure using a channel waveguide grating embedded in a planar waveguide is demonstrated. A segmented waveguide structure is used as a built-in grating fabricated simultaneously with the channel waveguide to simplify the fabrication process. The wavelength peak heights are almost constant and a spatial dispersion value of 6×105 was obtained.
