摘要：

We report on continuous-wave operation of first-order distributed feedback quantum-cascade lasers at lambda =11.8 mum, based on interminiband transitions in a chirped AlAs/GaAs superlattice. Short devices operate in continuous-wave up to similar to 30 K. The single-mode emission wavelength is continuously tunable with the temperature. A metallized surface-relief grating is used for feedback to achieve single-mode emission. (C) 2000 American Institute of Physics. [S0003-6951(00)04947-0].
