Quantum dot cascade laser [PDF]
Nanoscale Research Letters, 2014 Abstract We demonstrated an unambiguous quantum dot cascade laser based on InGaAs/GaAs/InAs/InAlAs heterostructure by making use of self-assembled quantum dots in the Stranski-Krastanow growth mode and two-step strain compensation active region design.

Quantum Cascade Laser Frequency Combs
Nanophotonics, 2016 It was recently demonstrated that broadband quantum cascade lasers can operate as frequency combs. As such, they operate under direct electrical pumping at both mid-infrared and THz frequencies, making them very attractive for dual-comb spectroscopy ...
