Abstract
A laser diode module including a laser diode assembly having a laser diode and a holder, a lens-fiber assembly having a lens and an optical fiber fixed in a given positional relationship, and a sleeve. The lens-fiber assembly includes a casing having a first hole and a second hole offset from the first hole. The lens is inserted and fixed in the first hole, and a ferrule in which the optical fiber is embedded is press-fitted with the second hole. The ferrule has a slant polished first end and a second end projecting from an end surface of the casing by a given distance. The lens and the ferrule are fixed in the casing so that a given distance is defined between the lens and the first end of the ferrule.
