    • MC simulation of double-resonant-phonon depopulation THz QCLs for high operating temperatures 

      Jirauschek C; Lugli P (2008)
      We theoretically investigate the temperature performance of GaAs-based double-resonant-phonon depopulation THz quantum cascade lasers. Based on an ensemble Monte Carlo simulation including both carrier-phonon and carrier-carrier ...
    • Monte Carlo simulation of resonant phonon THz quantum cascade lasers 

      Jirauschek C; Scarpa G; Lugli P; Manenti M (Springer, 2007)
      We report on Monte Carlo (MC) simulations aimed at the design and optimization of GaAs-based THz quantum cascade lasers. Results are presented for a GaAs/Al0.15Ga0.85As quantum cascade laser design based on LO phonon ...
    • THz quantum cascade lasers for operation above cryogenic temperatures 

      Belkin M; Vijayraghavan K; Vizbaras A; Jiang A; Demmerle F; Boehm G; Meyer R; Amann M; Matyas A; Chashmahcharagh R; Lugli P; Jirauschek C; Wasilewski ZR (SPIE, 2013)
      High temperature operation of terahertz (THz) sources based on quantum cascade lasers (QCLs) is discussed. THz QCLs are compact, powerful sources but can only operate at cryogenic temperatures. State-of-the art THz QCLs ...
