We show theoretically that the introduction of a cold electron gas into quantum microcavities induces efficient electron-polariton scattering. This process allows the condensation of the polaritons accumulated at the bottleneck to the final emitting state with a transition time of a few pico-seconds, opening the way to a new generation of low-threshold light-emitting devices.
