ABSTRACT:
A semiconductor laser diode optically coupled to an optical fiber is mounted on a stem. A cap having a light transmissive hole between the optical fiber and the semiconductor laser diode is fixed to the stem. A ball lens is fixed in the light transmissive hole. The ball lens has a refractive index of 1.9 or more and a diameter between 1.5 mm and 2.5 mm.
