Theoretical investigation on intrinsic linewidth of quantum cascade lasers
Quantum cascade lasers (QCLs) are unipolar laser sources relying on intersubband transitions in coupled multiple quantum well systems. The light emission can be tuned across the mid-infrared (mid-IR, from 3 to 20 micrometer) and Terahertz (THz, from 1.2 to 5 THz, or 60 to 250 micrometer) ranges of t...
