  1. GaAs/AlGaAs far-infrared quantum cascade laser

    … feasibility of an optically pumped inter subband farinfrared (40-100[mu]m) laser, using GaAs/ AlxGal-xAs heterostructures. The proposed design aims to use LO-phonon-mediated depopulation of the lower THz laser level to aid the intersubband laser population inversion. Interband recombination occurs …

  2. Development of intersubband terahertz lasers using multiple quantum well structures

    … for long-wavelength mode confinement, and farinfrared spectral measurement techniques are critical steps in achieving this goal. Conduction-band three-level subband systems in triple-quantum-well structures using GaAs/Alo.3Gao.7As heterostructures were proposed, designed, and simulated by a …
