Coherent control theory is used to show that one can manipulate biexciton vs exciton populations in semiconductor quantum dots (QDs) in a typical dissipative environment. Both aligned and randomly oriented quantum dots are considered, and population control is shown to be considerable. An application to CdSe QD shows that the proposed coherent control scenario results in a significant reduction in pump intensity for the onset of optical gain.
