Abstract:
1. An optical semiconductor device comprising: a lead frame having an aperture; a submount having transparency which is disposed on one surface of the lead frame to close the aperture of the lead frame; a semiconductor optical element which has an optical portion and which is mounted on a surface of the submount opposite to a surface on a side of the a aperture of the lead frame with the optical portion facing the aperture through the submount; a molding portion made of a non-transparent molding resin which exposes at least a region including the aperture on the other surface side of the lead frame and which encapsulates the lead frame, the semiconductor optical element and the submount; and a lens attached to the other surface of the lead frame to close the aperture of the lead frame, wherein the non-transparent molding resin includes a 70 wt % or more filler.
