Patent ID: 7217947

Claim:
A semiconductor light source device, comprising: a substrate; a plurality of semiconductor finger members of a first conductivity type on said substrate each having side walls perpendicular to said substrate; a multiple quantum well arrangement on each said side wall of said semiconductor finger members and including a plurality of quantum well layers of a first material interposed between barrier layers of a second material, said layers being perpendicular to said substrate and including an outside layer, said first and second material being selected from a class of materials which emit radiation of a particular wavelength upon application of a voltage between a first and a second ohmic contact, a plurality of semiconductor members of a conductivity type opposite to that of said finger members, with each positioned on an said outside layer of a respective one of said multiple quantum well arrangements such that each said multiple quantum well arrangement is sandwiched between a side wall of said semiconductor finger members and a semiconductor member of said plurality of semiconductor members; said first and second ohmic contacts being respectively positioned on said semiconductor finger members and said semiconductor, and wherein each said multiple quantum well arrangement includes a top and bottom surface and first and second opposed ends; and which includes; light reflectors positioned at each of said first and second ends of each said multiple quantum well arrangement; and a cladding layer positioned on said top surface to prevent generated light from exiting through said top surface.
