    摘要: A surface emitting laser including a semiconductor substrate, a semiconductor substrate, a first reflector formed on the semiconductor substrate, an active layer formed on the first reflector, a tunnel junction layer formed above a part of the active layer, a semiconductor spacer layer which covers the tunnel junction layer, a second reflector formed on the semiconductor spacer layer in a region above the tunnel junction layer, a first electrode formed in the periphery of the second reflector on the semiconductor spacer layer, and a second electrode electrically connected to a layer lower than the active layer, wherein a layer thickness of the semiconductor spacer layer in the region directly above the tunnel junction layer is thinner than the layer thickness of the semiconductor spacer layer in the region directly below the first electrode.
