Temperature performance analysis of terahertz quantum cascade lasers: Vertical versus diagonal designs

Alpar Matyas, Mikhail A. Belkin, Paolo Lugli, and Christian Jirauschek
Resonant phonon depopulation terahertz quantum cascade lasers based on vertical and diagonal lasing transitions are systematically compared using a well established ensemble Monte Carlo approach. The analysis shows that for operating temperatures below 200 K, diagonal designs may offer superior temp ... [Appl. Phys. Lett. 96, 201110 (2010)] published Fri May 21, 2010.
