Surface emitting laser element
Abstract:
Disclosed is a surface emitting laser element capable of reducing threshold current. A surface emitting laser element according to an embodiment includes a semiconductor portion having a first semiconductor layer and a second semiconductor layer, a first reflector disposed at the first semiconductor layer side of the semiconductor portion, and a second reflector disposed at the second semiconductor layer side of the semiconductor portion. Particularly includes a second electrode disposed between the second semiconductor layer and the second reflector and connected to the second semiconductor layer, a connecting electrode disposed laterally around the second reflector and connected to the second electrode, and a current confinement portion disposed between the second semiconductor layer and the connecting electrode and capable of reflecting light from the semiconductor portion.
