Alloy composition effects on the gain and the differential gain for CdZnTe based II–VI semiconductor lasers

We study the variation of the gain and the differential gain for a quantum well laser based on the CdZnTe alloys. We calculate theoretically the optical gain of CdZnTe based quantum well laser, as function of the alloys composition for various values of carrier’s densities. Our study is based on the...

Description
Summary:We study the variation of the gain and the differential gain for a quantum well laser based on the CdZnTe alloys. We calculate theoretically the optical gain of CdZnTe based quantum well laser, as function of the alloys composition for various values of carrier’s densities. Our study is based on the parabolic model with the intraband relaxation taken into account. Finally, we investigate how the composition alloys affects the differential gain of quantum well lasers.
