摘要： A surface emission laser formed of a group III nitride semiconductor includes a first conductivity type first clad layer; a first conductivity type first guide layer on the first clad layer; a light-emitting layer on the first guide layer; a second guide layer on the light-emitting layer; and a second conductivity type second clad layer on the second guide layer. The first or second guide layer internally includes voids periodically arranged at square lattice positions with two axes perpendicular to one another as arrangement directions in a surface parallel to the guide layer. The voids have a polygonal prism structure or an oval columnar structure with a long axis and a short axis perpendicular to the long axis in the parallel surface, and the long axis is inclined with respect to one axis among the arrangement directions of the voids.

摘要： A light source device comprising a filament showing high electric power-to-visible light conversion efficiency is provided. The light source device of the present invention comprises a translucent gastight container, a filament disposed in the translucent gastight container, and a lead wire for supplying an electric current to the filament. The filament comprises a substrate formed from a metal material and a visible light-absorbing film covering the substrate. The visible light-absorbing film is transparent to lights of infrared region. The reflectance of the substrate for visible lights is thereby made low, and the reflectance of the substrate for infrared lights is thereby made high. Therefore, radiation of infrared lights is suppressed, and visible luminous efficiency can be enhanced.

摘要： A method for manufacturing a surface emitting laser made of a group-III nitride semiconductor by an MOVPE method includes: (a) growing a first cladding layer of a first conductive type on a substrate; (b) growing a first optical guide layer of the first conductive type on the first cladding layer; (c) forming holes having a two-dimensional periodicity in a plane parallel to the first optical guide layer, in the first optical guide layer by etching; (d) supplying a gas containing a group-III material and a nitrogen source and performing growth to form recessed portions having a facet of a predetermined plane direction above openings of the holes, thereby closing the openings of the holes; and (e) planarizing the recessed portions by mass transport, after the openings of the holes have been closed, wherein after the planarizing at least one side surface of the holes is a {10-10} facet.
