Patent ID: 7192199

Claim:
An optical semiconductor module, comprising: an optical guide having an optical coupling end, the optical guide being configured to guide an optical signal; an optoelectronic ferrule having a coupling face, provided with electrode pads on the coupling face and a guiding through-hole having an opening on the coupling face, in which the optical guide is inserted; a semiconductor device arranged to face the coupling face with a gap, and electrically coupled to the electrode pads, the semiconductor device including a light emitting or light detecting section facing to the optical coupling end; a first resin layer located in the gap between the light emitting or light detecting section and the optical coupling end, the first resin layer optically coupling the light emitting or light detecting section to the optical coupling end; a second resin layer applied to the gap around the first resin layer; and a groove formed in the optoelectronic ferrule and communicated with the guiding through-hole.
