The polarization properties of four-wave interaction on polymer films with bacteriorhodopsin that possess anisotropically saturating nonlinearity are studied both theoretically and experimentally. The amplitude and the polarization of the diffracted wave for recording material with anisotropically saturating nonlinearity are calculated. Low saturation intensity allows the operation of the polarization of low-intensity signals to be realized. It is shown that control of the diffractive wave polarization is possible only with the variation of the light recording intensity.
