Semiconductor device can be connected to an external optical fiber, by providing a short optical fiber, optically coupled to a semiconductor, which is held in a ferrule having the same diameter as an external ferrule of the external fiber. The semiconductor device comprises an optical semiconductor laser diode, a short optical fiber optically coupling at its first end face with the optical semiconductor laser diode, a ferrule for housing the optical fiber, and a sleeve which has an inner diameter slightly larger than an outer diameter of the ferrule and into which the ferrule is inserted. The connection to an external optical fiber is given by inserting a connector of the external optical fiber into the sleeve. The present invention provides compact optical semiconductor device suitable for automatic mounting thereof.
