1. A wavelength multiplexing transceiver for wavelength multiplexing in an optical communication network comprising:

  • first and second slab waveguides;

    a first optical waveguide for supplying an output light from said first slab waveguide to an input/output optical fiber;

    a second optical waveguide for supplying an incident light from said input/output optical fiber to said second slab waveguide;

    a optical coupler for branching an optical path of said input/output optical fiber to said first and second optical waveguides;

    a laser array optically coupled to one end of said first slab waveguide, to the other end of which said optical coupler is coupled; and

    a light receiving element array optically couple to one end of said second slab waveguide, to the other end of which said optical coupler is coupled,said first and second slab waveguides, first optical waveguide, second optical waveguide, and optical coupler being commonly formed on a substrate.
