Since the concept of quantum cascade laser (QCL) first proposed in 1997, the technology of QCL has grown rapidly and QCLs have been applied in many aera such as gas sensing and optical communication. The property of unipolar and subbands transition makes quantum cascade laser (QCL) ideal both mid-in...
