Abstract
The proposed research is a study of designing high-efficiency Mid-IR quantum cascade lasers (QCL). This thesis explores "injector-less" designs for achieving lower voltage defects and improving wall plug efficiencies through highly strain-balanced structures and minimized injector regions. This work contains experimental design work for testing and evaluating Mid-IR QCL performance, simulation work for verifying wavefunction and energy alignment, as well as, Monte Carlo transport simulations for evaluating designs, and finally measuring lasing and spontaneous emission performance for various designs.
