Patent ID: 8755423

Claim:
A surface emitting laser module comprising: a light emitting diode that includes a semiconductor substrate, a light emitting region disposed on the semiconductor substrate, a lens integrated into the light emitting region, and a retaining section integrated into the semiconductor substrate to surround the light emitting region into which the lens is integrated, and that emits light from the light emitting region in a vertical direction with respect to a principal surface of the semiconductor substrate; an external optical waveguide that is fitted into and retained by the retaining section and guides light transmitted by the lens and emitted from the light emitting diode; and a stem to which the light emitting diode and external optical waveguide are fixed, wherein the light emitted from the light emitting region proceeds in a vertical direction towards the external optical waveguide with respect to the principal surface of the semiconductor substrate, wherein the retaining section has a concave step shape in cross section disposed above the lens, wherein the external optical waveguide is a reflected-light prevention optical fiber whose light receiving surface has a predetermined angle with respect to the semiconductor substrate, and the retaining section has an angle thereof conformed to the predetermined angle so that the reflected-light prevention optical fiber can be fitted into the retaining section.
