Abstract:
A semiconductor light-receiving device comprising:a substrate having a groove for a buried optical fiber, said optical fiber groove being formed in a main surface of the substrate to extend from one end of the substrate to the other end thereof;an optical fiber buried in said optical fiber groove to be covered with a resin material;a semiconductor light-receiving element having a light-receiving portion at a surface thereof in opposing relation to the main surface of said substrate, said semiconductor light-receiving element being disposed on the main surface of said substrate via a bump such that said light-receiving portion is opposed to said optical fiber;an optical member disposed in said substrate to intersect said optical fiber, said optical member reflecting or diffracting signal light propagated through said optical fiber and irradiating said light-receiving portion of said semiconductor light-receiving element with the reflected or diffracted signal light; anda holder disposed in said substrate to suppress a temperature-dependent variation in a width of said optical fiber groove.
