Abstract

All-optical holography of azobenzene-liquid-crystal (ALC) doped nematic liquid crystals (NLC) is investigated by means of polarization and intensity grating methods. The holographic grating is formed upon a total optical power as low as 200 μW/cm² without any external biases, and can be switched within hundreds of milliseconds. The polarization dependence of the probe beam on the diffraction intensity reveals that the grating formation is attributed to reorientation and order-parameter change of the NLC molecules induced by the photoisomerization of the ALC molecules.
