Abstract
A new lasing scheme with sequential two-photon emission in the gain module for terahertz quantum cascade laser (THz QCL) is proposed and experimentally demonstrated. THz QCLs based on MBE- and MOCVD-grown structures with two-photon design have a lasing frequency of 3.8 THz and maximum operation temperature around 100 K.
