LIGHT-EMITTING DEVICE
First Claim
1. A light-emitting device comprising:
- a first cladding layer;
an active layer formed above the first cladding layer; and
a second cladding layer formed above the active layer, whereinthe active layer has a first side surface, and a second side surface parallel to the first side surface;
at least a portion of the active layer constitutes a gain region;
the gain region has a first end surface disposed on the first side surface side and a second end surface disposed on the second side surface side, and extends from the first end surface to the second end surface in the direction inclined to the normal to the first side surface as viewed from above;
the second end face is orthogonal to the direction in which the gain region extends as viewed from above;
a reflecting part is disposed on the second end face; and
a part of the light generated in the gain region is reflected in the reflecting part disposed on the second end face and is emitted from the first end surface.

Abstract
The light-emitting device 100 of the present invention has a first cladding layer 106; an active layer 108 formed above the first cladding layer 106; and a second cladding layer 110 formed above the active layer 108, wherein the active layer 108 has a first side surface 107, and a second side surface 109 parallel to the first side surface 107; at least a portion of the active layer 108 constitutes a gain region 180; the gain region 180 has a first end surface 140 disposed on the first side surface 107 side and a second end surface 142 disposed on the second side surface 109 side, and extends from the first end surface 140 to the second end surface 142 in the direction inclined to the normal to the first side surface 107 as viewed from above; the second end face 109 is orthogonal to the direction in which the gain region 180 extends as viewed from above; a reflecting part 150 is disposed on the second end face 109; and a part of the light 10 generated in the gain region 180 is reflected in the reflecting part 150 disposed on the second end face 142 and is emitted from the first end surface 140.
