Abstract
A surface emitting laser according to one embodiment of the disclosure includes a stacked structure including, in order, a first DBR layer, an active layer, a second DBR layer, and a first electrically conductive contact layer. The stacked structure further includes a second electrically conductive contact layer and a two-dimensional electron gas generation layer between the first DBR layer and the active layer or in the first DBR layer. The surface emitting laser further includes a first electrode layer in contact with the first electrically conductive contact layer and a second electrode layer in contact with the second electrically conductive contact layer.
Claims8
A surface emitting laser, comprising:
- a substrate;
- a stacked structure includes:
- a first distributed bragg reflector (DBR) layer, an active layer, a second DBR layer, and a first electrically conductive contact layer, in this order from a side of the substrate, and
- a second electrically conductive contact layer and a two-dimensional electron gas generation layer between the first DBR layer and the active layer or in the first DBR layer,
- wherein the second electrically conductive contact layer is at a position more adjacent to the active layer than the two-dimensional electron gas generation layer;
- a first electrode layer in contact with the first electrically conductive contact layer;
- and
- a second electrode layer in direct contact with a surface of the second electrically conductive contact layer adjacent to the active layer.
