Abstract: An interband resonant tunneling intersubband transition laser is disclosed, and includes a semiconductor substrate (120), and a first cladding layer (150b), an active region structure layer (110) and a second cladding layer (150a) formed on the semiconductor substrate. The active region structure layer includes quantum well layers (110a) and quantum barrier layers (110b) that are alternately stacked and have a broken energy bandgap. Thus, the interband resonant tunneling intersubband transition laser operates in a cascade mode in which an intersubband radiative transition and interband tunneling of carriers consecutively and repetitively occur in the active region structure layer, and thus can achieve a high output from a simple, compact structure.
