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.
