ABSTRACT:
An optical wavelength multiplexing and demultiplexing device includes a first waveguide and a plurality of waveguides having different propagation constants. The first waveguide is caused to be coupled with the plurality of waveguides in different modes. The plurality of waveguides have different structures or different indices so as to provide different propagation constant from each another. According to the optical wavelength multiplexing and demultiplexing device, light components having various wavelengths and modes can be simultaneously multiplexed or demultiplexed.
