Coherence in Optics and Transport in Terahertz Quantum Cascade Lasers

Author

  • Carsten Weber
  • Andreas Wacker

Summary, in English

Coherence in optics and transport is investigated for quantum cascade lasers. While coherence provides oscillations in the gain recovery if the tunnel coupling surpasses the broadening, incoherent hopping transport can fail in the opposite case. (C) 2008 Optical Society of America
