    摘要: A light-emitting device according to an embodiment of the present disclosure includes a laminate. The laminate includes an active layer, and a first semiconductor layer and a second semiconductor layer sandwiching the active layer. This light-emitting device further includes a current constriction layer having an opening and a vertical resonator including a first reflecting mirror having a concave-curved shape on the first semiconductor layer side and a second reflecting mirror on the second semiconductor side. The first reflecting mirror and the second reflecting mirror sandwich the laminate and the opening. This light-emitting device further includes an optically transparent substrate between the first reflecting mirror and the laminate. The optically transparent substrate has a first convex portion having a convex-curved shape and one or more second convex portions on a surface on the side opposite to the laminate. The first convex portion is in contact with the first reflecting mirror. The one or more second convex portions are provided around the first convex portion. The one or more second convex portions each have a height greater than or equal to a height of the first convex portion, and an end on the first reflecting mirror side has a convex-curved shape.

    摘要: A laser diode with an improved kink level in the L-I characteristic and capable of obtaining a stable high output in a horizontal transverse mode is provided. The laser diode includes an active layer made of nitride III-V compound semiconductor containing at least gallium (Ga) in 3B-group elements and at least nitrogen (N) in 5B-group elements, an n-type compound semiconductor layer provided on one of faces of the active layer, and a p-type compound semiconductor layer provided on the other face of the active layer. A region closest to the active layer, in the n-type compound semiconductor layer is a high-concentration region whose impurity concentration is higher than that of the other n-type regions.
