英文摘要	A quantum cascade laser includes a substrate having first, second, third, and fourth regions; a stacked semiconductor layer including n-type lower and upper conductive layers, a core layer having a mesa structure, and a cladding layer; first and second buried layers disposed on side surfaces of the core layer and above the substrate; a first electrode disposed on the upper conductive layer above the first region; and a second electrode disposed on the lower conductive layer above the fourth region. The core layer is disposed on the lower conductive layer above the second region. The upper conductive layer is disposed on the first buried layer and the core layer. The cladding layer is disposed on the upper conductive layer above the second region. The substrate and the cladding layer are formed of an undoped or semi-insulating semiconductor. The first and second buried layers are formed of a semi-insulating semiconductor.
