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...

| Summary: | 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 operating current densities make this design a viable alternative. |
