Influence of optical activity on properties of a phase conjugate wave generated in a photorefractive BSO crystal

A rigorous method for analyzing the effect of optical activity on a phase conjugate wave (PCW) generated in photorefractive Bi/sub 12/SiO/sub 20/ (BSO) is described. Using the method, the PCW intensity and its polarization angle versus the input polarization angle of the probe beam are numerically evaluated for two transverse configurations, with a static electric field generated approximately along the [001] direction or the [110] direction, respectively. Both the observed PCW intensity and its polarization angle are in reasonable agreement with the theory. The result indicates that optical activity has a pronounced influence on the properties of the PCW. The analysis is applicable to any isotropic photorefractive crystal with optical activity.<
