Abstract
A semiconductor light-receiving device comprises a substrate, an optical fiber, a semiconductor light-receiving element, an optical member, and holders. A groove for a buried optical fiber is formed in the main surface of the substrate to extend from one end of the substrate to the other end thereof. The optical fiber is buried in the optical fiber groove and covered with a resin material. The semiconductor light-receiving element has a light-receiving portion at a surface thereof in opposing relation to the main surface of the substrate and is disposed on the main surface of the substrate via bumps such that the light-receiving portion is opposed to the optical fiber. The optical member is disposed in the substrate in an intersecting relationship with the optical fiber to reflect or diffract signal light propagated through the optical fiber and irradiate the light-receiving portion of the semiconductor light-receiving element with the reflected or diffracted signal light. The holders are provided in the substrate to suppress a temperature-dependent variation in the width of the optical fiber groove.
