Abstract
Laser-like emissions from semiconductor microcavities at low temperature have attracted considerable attention recently because of the possibility of realizing a nonequilibrium condensate by use of cavity-polaritons.1 In this paper we present experimental studies of optical properties of a microcavity near the lasing threshold. We show that the minimum lasing threshold is achieved when the cavity is tuned significantly below the exciton line center. By comparing emission spectra with reflectivity spectra, we also show that well-resolved doublet in the emission spectra near the lasing threshold are not associated with cavity-polaritons.
