Abstract
Realization of an optically controlled transparency possessing a nonlinear holographic modulation characteristic containing region with positive and n egative slope is demonstrated to be feasible. The transparency filter is ba sed on a glassy chalcogenide photoconductor-nematic liquid crystal structur e. A tenfold drop in the diffraction efficiency over the negative-slope reg ion was obtained in the experiment. (C) 2000 MAIK "Nauka/Interperiodica".
