Abstract
An optical semiconductor module which is connected to an optical fiber to introduce light from an optical semiconductor element into the optical fiber. The module comprises a holder which holds the semiconductor element, a housing which has a rod lens positioned therein and to which the holder is connected by fitting engagement made between one end of the housing and one end of the holder such that the optical axis of the semiconductor element and the optical axis of the rod lens coincide with each other, and a receptacle to which the optical fiber is connected, the receptacle being connected to the other end of the housing adjustably within a plane which perpendicularly intersects the optical axis of the optical fiber such that light from the semiconductor element that passes through the rod lens enters the optical fiber.
