Short period InGaAs/AlInAs THz quantum cascade laser in thin double metal cavities operating up to 188K
Sebastian Gloor, David Stark, Martin Frankié +4
We present a two-well terahertz (THz) quantum cascade laser designed for high temperature operation based on the InGaAs/AlInAs material system. The lighter effective mass and highe…
