Abstract:
A quantum cascade laser includes: a substrate including a substrate end face; a semiconductor laminate having a laminate end face and a core extending in an axial direction; a first electrode disposed on the semiconductor laminate; a second electrode disposed on a back surface of the substrate; an insulating film disposed on the laminate end face and the first electrode; and a first metal film disposed on the laminate end face, the insulating film and the first electrode, the insulating film being between the first metal film and the semiconductor laminate. The substrate end face and the laminate end face extend along a reference plane intersecting the axial direction. The substrate end face has a first area and a second area arranged in a direction from the back surface to a principal surface of the substrate, and the first metal film has an end on the second area.

Claim (Index 1):
A quantum cascade laser comprising:\n a substrate including a principal surface, a back surface, and a substrate end face, the principal surface and the back surface being arranged in a first direction, the principal surface being opposite to the back surface, the substrate end face intersecting a second direction, and the second direction intersecting the first direction; a semiconductor laminate disposed on the principal surface of the substrate, the semiconductor laminate having a laminate end face, and the semiconductor laminate including a core layer extending from the laminate end face in the second direction, and a cladding layer disposed on the core layer, the substrate end face and the laminate end face extending along a reference plane intersecting the second direction; a first electrode disposed on the semiconductor laminate; a second electrode disposed on the back surface of the substrate; an insulating film disposed on the laminate end face and the first electrode; and a first metal film disposed on the laminate end face, the insulating film and the first electrode, the insulating film being between the first metal film and the semiconductor laminate, the semiconductor laminate and the substrate being disposed between the first electrode and the second electrode, the substrate end face having a first area and a second area, the first area and the second area being arranged in a direction from the back surface of the substrate to the principal surface thereof, and the first metal film having an end on the second area.
