Abstract
A surface-emitting semiconductor laser device having reduced device resistance, a method for fabricating the device and a surface-emitting semiconductor laser array employing the device are provided. The laser device comprises a lower reflector layer structure and an upper reflector layer structure, formed on a p-type semiconductor substrate. An etching blocking layer, a current confinement layer, and an active layer are formed in that order from below between the lower and upper reflector layer structures. The portion over the etching blocking layer is formed into a mesa shape.
