<p>An optical multiplexer/demultiplexer (1) comprises a plurality of first waveguides (3), a first slab waveguide (4), an array-waveguide diffraction grating (5) with a plurality of waveguides, a second slab waveguide (6) and a plurality of second waveguides (7), and the waveguides are connected in that order. The ratio of the interval between the first waveguides (3) in the connection with the first slab waveguide (4) to the interval between the second waveguides (7) in the connection with the second slab waveguide (6) is different from the ratio of the focal distance of the first slab waveguide (4) to the focal distance of the second slab waveguide (6).</p> |
