Abstract

We study the phase effects on the exciton polariton amplifier excited by the signal, pump, and idler lasers simultaneously. The signal amplification can be largely enhanced or depressed in this arrangement, compared with that where only the signal and pump lasers are applied. Moreover, a signal polariton switch can be achieved by controlling the excitation phases and it has a high on-off ratio under certain excitation intensities. For a typical GaAs-AlGaAs microcavity, the switching time is about 50 ps and the operating power is about 50 mW.
