Patent ID: 7983319

Claim:
A surface-emitting type semiconductor laser, comprising: a substrate; a vertical resonator above the substrate, the vertical resonator including: a first mirror, an active layer and a second mirror disposed in this order from the substrate; and a plurality of unit resonators, an emission region of each of the plurality of unit resonators having a diameter that oscillates in a single-mode, each of the plurality of unit resonators having an identical diameter, and laser light of each of the unit resonators has an identical wavelength, wherein each unit resonator has a rectangular shape in plan view and includes an aperture section in each corner of the unit resonator, the aperture section being formed of an insulating material that is disposed on the first mirror, a current aperture layer is disposed around each aperture section, the current aperture layer being formed of an insulating material that is disposed between the active layer and the second mirror, and the emission region is defined by an outer edge of the current aperture layer formed around each aperture section.
