摘要： Degradation in an optical characteristic attributed to thermal stress and mechanical external force is suppressed in an optical component that a part of a waveguide type optical device is fixed to a convex portion of a mount. First and second optical device support bases (301, 302), opposed to each other, are fixed to a second waveguide type optical device (202) at clearances away from a mount (210). First and second presser support bases (311, 312) are disposed on the mount (210), and are also opposed to each other. A presser member (313) is disposed on the first and second optical device support bases (301, 302), and is fixed by the first and second presser support bases (311, 312) at clearances away from the first and second optical device support bases (301, 302). The second waveguide type optical device (202) and the first and second optical device support bases (301, 302) are not fixed to the surrounding members thereof, and are slidable in a direction parallel to the surface of the mount (210).

摘要： 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 101 includes dummy patterns 17 provided on both sides of each optical waveguide 13 of the interferometer A1.
