ABSTRACT:
A light receiving module of the present invention includes a semiconductor substrate formed with a guide groove and a mount groove for receiving an optical fiber and a light receiving device, respectively. The mount groove includes a mount surface to which the light receiving device is affixed. The mount surface is contiguous with the output end of the guide groove. The light receiving device is inserted into the accurately formed guide groove and then affixed to the mount surface of the groove. The fiber and light receiving device can therefore be accurately positioned relative to each other. This, coupled with the fact that the optical coupling length is reduced because of the close contact of the fiber and light receiving device, implements adjustment-free mounting and therefore high optical coupling.
