            Abstract : 
We present a study of a microcavity polariton system in the presence of an optically induced electron gas. Angle resolved photoluminescence measurements with nonresonant excitation show enhanced emission from the k /spl ap/ 0 states as the electron density is increased. This indicates that electron-polariton scattering can assist in relaxing the polariton bottleneck.
