Abstract
Two-beam coupling gain of constant sign was observed in hybrid planar/homeotropic nematic cells under a nonbiased square-wave ac field. Charge photogeneration was induced by using one layer of photoconducting polymer. With writing beams of equal intensities, gains up to 6% were observed in ∼10μm thick samples when the amplitude of the applied field was of the order of 1Vμm−1 at 10Hz. The gain decreased gradually when the frequency was increased, vanishing above 100Hz.
