چکیده
|
We present an optimized design for gaas/algaas quantum cascade lasers operating at 4.1thz. this was based on a three-well active module with diagonal radiative transition. this was performed by modifying the existing model structure, to reduce the parasitic anticrossings (leakage currents) as well as the optical gain linewidth. while the gain fwhm was reduced by more than 50% the gain peak was increased by about 23.3%.
