Low threshold step well quantum cascade laser emitting at 3 THz
(2009)2009 Conference on Lasers and Electro-Optics and 2009 Conference on Quantum electronics and Laser Science ConferenceA resonant-phonon THz quantum cascade laser based on Al 0.03 Ga 0.097 As step well is demonstrated. Maximum pulsed operating temperature is 123 K, with threshold current densities as low as 110 A/cm 2 at 10 K and 175 A/cm 2 at 100 K.Other Conference Item -
Low divergence single mode edge emitting double metal Terahertz quantum cascade laser
(2009)2009 Conference on Lasers and Electro-Optics and 2009 Conference on Quantum electronics and Laser Science ConferenceWe present the use of a third order distributed feedback waveguide for double metal THz quantum cascade laser as a successful design to obtain high slope efficiency of 50 mW/A, spectral emission control and narrow single lobed far field (5degtimes 8deg).Other Conference Item -
