We report on an experimental Study of the microcavity polariton linewidth in an AlAs/AlGaAs microcavity containing GaAs quantum wells (QW) in which a variable density electron gas is photogenerated. The linewidth of the lowest polariton branch shows a clear suppression while that of the other branches show enhancement at narrow detuning energy ranges. A transformation is observed from a strong to weak exciton-cavity, mode coupling at a very low photoexcitation intensity. (C) 2001 Published by Elsevier Science Ltd. References: 16
