Patent ID: 8465993

Claim:
A fabrication method of a vertical cavity surface emitting laser, the fabrication method comprising: preparing a substrate which includes a semiconductor layer, the semiconductor layer including a first semiconductor multilayer reflector of a first conductive type, an active region, a current narrowing layer which is conductive, and a second semiconductor multilayer reflector of a second conductive type; forming an electrode which defines a beam window on the second semiconductor multilayer reflector; forming a first insulating layer, which is comprised of a material having a first refractive index to an oscillation wavelength, to cover the beam window; after covering the beam window, forming an oxidization region and a conductive region surrounded by the oxidization region inside of a current narrowing layer by oxidizing the current narrowing layer; and forming, on the first insulating film, a pattern of a second insulating layer that substantially corresponds to a center of the conductive region and is smaller than a radius of the conductive region, the second insulating layer being comprised of a material having a second refractive index that is greater than the first refractive index.
