ABSTRACT:
An optical multiplexer is equipped with at least one input channel optical waveguide provided on an optical waveguide substrate, a first slab optical waveguide, a channel optical waveguide array formed from a plurality of optical waveguides having a prescribed waveguide length, a second slab optical waveguide and at least one output channel optical waveguide sequentially connected in a tandem arrangement; and phase adjustment to achieve the same phase distribution in the channel optical waveguide array.
