Abstract
We study the behavior of polarizations and phases in an exciton polariton amplifier based on a semiconductor microcavity. The parametric amplification is strongly influenced by combining the polarizations and relative phase of the lasers exciting the signal, pump, and idler states. In this way, significantly, the light emitting from the signal state can be manipulated continuously from the left to the right circular polarization or vice versa. This manipulation of the signal polarization can be used to encode information and provide stable source of polarized light in the spin-dependent optoelectronic devices.
