Abstract
Optical gain has been demonstrated in strongly confined CdSe quantum dots. A gain bandwidth of approximately 0.5 eV has been experimentally demonstrated in these structures.1 As a consequence of the Pauli blocking in the lowest conduction band, only the two-electron- hole-pair-excitation (biexciton) and the one-electron- hole-pair-excitation (exciton) states contribute to the gain. In this presentation, for the first time to our knowledge, we show theoretically that the biexciton-to-exciton transitions are important in forming gain in quantum dots (QDs).
