ABSTRACT:
An optical semiconductor module for holding an optical fiber inserted in a ferrule and for coupling light into the optical fiber, including: a semiconductor light-emitting device; a lens for converging light emitted from the semiconductor light-emitting device; a holder having a cylindrical part for holding the semiconductor light-emitting device and the lens therein and for allowing the adjustment of a position where the semiconductor light-emitting device is to be fixed and thereby enabling the spacing between the semiconductor light-emitting device and the lens to be adjusted, the lens being fixed inside the cylindrical part and the semiconductor light-emitting device also fixed inside the cylindrical part with the optical axis thereof aligned with the lens; and a receptacle having an inner cylinder for holding the ferrule therein, and joined to one end of the holder by butting end to end so as to allow the joining ends to be adjusted in directions perpendicular to the optical axis of the lens so that the light converged by the lens is focused on a light receiving end of the optical fiber.
