quantum cascade laser
Introduction
QCL
A quantum cascade laser is a very unique semiconductor laser that has been first demonstrated at Bell Laboratories in 1994.

Wikipedia has some nice information on QCLs: Quantum cascade laser

Features
  • self-consistent Schrödinger and Poisson equations
  • 8x8 k.p Schrödinger equation
  • strain
  • Non-equilibrium Green's function (NEGF) method for calculating I-V curves and gain
