Degenerate four-wave mixing from anisotropic artificial Kerr media

Abstract

Four-wave mixing from composite artificial Kerr media consisting of ellipsoidal microparticles suspended in a host liquid is discussed. Calculations of nonlinear grating formation and decay times are given in a dynamic model that includes the effect of random collisions on the particulates. Phase-conjugate efficiencies for a model configuration are given as well as operating limits imposed by particulate scattering from the composite.
