Abstract
The coherent control of the exciton population in quantum wells (QW's) is considered. For cavity-free QW's a pulse leaves the QW empty of excitons subsequent to its passage. For the microcavity, in addition to certain pulses, specially tailored pulses with nonzero area are also optimal. The coherent depopulation is a strong-coupling effect and is due to the phase shift in the self-consistent Maxwell field (i.e., including the local-field effect associated with the exciton resonance) in the cavity that occurs in the course of a vacuum-field Rabi flop.
