ABSTRACT:
To provide surface-emitting type semiconductor lasers and methods of manufacturing the same in which the polarization direction of laser light can be readily controlled, a surface-emitting type semiconductor laser includes a vertical resonator above a substrate. The vertical resonator includes a first mirror, an active layer and a second mirror disposed in this order from the substrate. The vertical resonator has a plurality of unit resonators. An emission region of each of the unit resonators has a diameter that oscillates in a single-mode.
