Low-threshold terahertz quantum-cascade lasers with one-well injector operating up to 174 K

Low-threshold terahertz quantum-cascade lasers with one-well injector operating up to 174 K

We report operation of v ~ 2.7 THz quantum-cascade lasers (QCLs) up to 174 K. A new three-well active region, one-well injector scheme is utilized to lower the operating current densities. While the temperature performance of this design is comparable to that of the best published THz QCLs, lower op...
