Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. Rakić, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…

Impact of Carrier Injector Design on the Threshold of Interband Cascade Lasers
T. Sato, B. Petrović, R. Weih +5
We theoretically investigate how the injector region design of interband cascade lasers (ICLs) impacts the threshold carrier and current densities. The model combines a polarizatio…
