摘要:
A surface-emitting laser according to an embodiment of the present disclosure includes a current constriction region having an opening and formed by impurities injected into a laminate from side of a second semiconductor layer; and a first DBR layer on side of a first semiconductor layer and a second DBR layer on the side of the second semiconductor layer having the laminate interposed therebetween at a position facing the opening. At the opening, an opening diameter close to the first DBR layer is larger than an opening diameter close to the second DBR layer.
