PURPOSE: An arrayed waveguide grating optical multiplexer/demultiplexer is provided to reduce manufacturing costs and to improve a yield by easily and precisely producing. CONSTITUTION: The optical wavelength multiplexer/demultiplexer has one or more optical input waveguides(2) provided side by side, a first slab waveguide(3) connected to the outgoing side of the optical input waveguides(2), an arrayed waveguide(4) comprised of a plurality of channel waveguides(4a) which are connected to the outgoing side of the first slab waveguide(3) and are provided side by side in different lengths, respectively. The length of adjacent channel waveguides(4a) are different from each other by a predetermined length difference, a second slab waveguide(5) connected to the outgoing side of the arrayed waveguide(4), and a plurality of optical output waveguides(6) provided side by side and connected to the outgoing side of the second slab waveguide(5).
