Abstract
In this work, theoretical formulation for the computation of electronic structure and gain spectra of CdSe/ZnSe quantum dot has been developed in the framework of multi-band k.p. approach. The optical gain of CdSe/ZnSe quantum dot has been determined. The gain is found to increase with carrier density but it is found to decrease as we increase the temperature.
