Beschreibung
Zusammenfassung:	A planar lightwave circuit according to the present invention includes at least two interferometers each of which includes a plurality of optical waveguides, and dummy patterns that are provided on both sides of each of the optical waveguides of an interferometer, having an optical waveguide density lower than the highest optical waveguide density, of the interferometers. The optical waveguide density of an interferometer A1 is higher than the optical waveguide density of the interferometer A2. Therefore, the planar lightwave circuit includes dummy patterns provided on both sides of each optical waveguide of the interferometer A1.
