摘要： An optical component is provided that is stable against temperature change in usage environment and that a first planar lightwave circuit and a second planar lightwave circuit, having different refractive indices, are butt jointed on the end surfaces thereof such that groups of multiple optical waveguides respectively formed on the planar lightwave circuits are optically coupled to each other. In an optical component (500), a first planar lightwave circuit (501) having a first refractive index n 1 and a second planar lightwave circuit (502) having a second refractive index n 2 different from the first refractive index n 1 are butt jointed on the end surfaces thereof perpendicular to an optical axis direction. First to n-th optical waveguides (where n is an integer greater than or equal to 2) are formed on each of the first and second planar lightwave circuits. The first and second planar lightwave circuits are aligned and jointed such that the position of an i-th optical waveguide (where i is an integer greater than or equal to 1 and less than or equal to n) of the first planar lightwave circuit and that of an i-th optical waveguide of the second planar lightwave circuit are matched on a joint interface. An angle Õ i formed by the i-th optical waveguide of the first planar lightwave circuit and a normal of the interface is configured to vary in accordance with a value of i within a range satisfying the Snell's law.

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).
