Abstract:
A quantum cascade laser includes: a laser structure having a first region, a second region, and a third region, the first region having an end face; a high-specific resistance region disposed on a principal surfaces of the first and second regions; a metal layer disposed on a principal surface of the third region; a dielectric film disposed on the end face and the high-specific resistance region; and a reflective metal film disposed on the dielectric film, the end face and the high-specific resistance region. The first to third regions are arranged in a direction of a first axis. The laser structure has a semiconductor mesa and a semiconductor base. The semiconductor base mounts the semiconductor mesa. The dielectric film has a difference in level at a boundary between the first and second regions, and the terrace extends in a direction of a second axis intersecting that of the first axis.

Claim (Index 4):
The quantum cascade laser according to  claim 3 , wherein\n the inorganic insulating film further has a third portion on the principal surface of the third region, the first portion, the second portion and the third portion of the inorganic insulating layer extend in the direction of the second axis, the third portion of the inorganic insulating film has a third thickness different from the second thickness, and the second portion and the third portion of the inorganic insulating film are adjoined to each other to form a groove.
