Abstract: In a novel tunable semiconductor intersubband laser (111), the lasing transition (41) is a non-resonant tunneling transition, with the frequency of the emitted photon depending on the electrical bias across the multi-period active region (12) of the laser. The laser can be designed to emit in the mid-IR, and can advantageously be used for, e.g., trace gas sensing.
