Abstract: Based on a microscopic many-particle theory we study the amplification ofpolaritons in a multiple-quantum-well resonant photonic crystal. For theBragg-spaced multiple quantum wells under investigation we predict that in atypical pump-probe setup four-wave mixing processes can lead to an unstableenergy transfer from the pump into the probe and the background-free four-wavemixing directions. We find that under certain excitation conditions thisphase-conjugate oscillation induced instability can lead to a largeamplification of the weak probe pulse.
