New Insights Reached via Graded-Interfaces Modeling: How High-Power, High-Efficiency Mid-Infrared QCLs Work
Graded-interfaces modeling unveils key features of high-power, high-efficiency quantum-cascade lasers (QCLs): direct resonant-tunneling injection from a prior-stage, low-energy state into the upper-laser (<i>ul</i>) level, over a wide (~50 nm) multiple-barrier region; and a new type of p...
