Abstract

Azobenzene polymer and liquid crystal are mixed in certain ratio

then the mixture is injected into cells. Nonlinearly photoinduced birefringence takes place when linearly pola-rized ultraviolet is applied with the pattern photomask covering on the cells

which results in the formation of azobenzene polymer doped liquid crystal grating. The samples are checked by optical microscope and He-Ne laser. The results indicate the samples have clear grating structure

and the diffraction efficiencies can be modulated by electric field. It is important that the driving voltage of the sample is low enough to match the driving integrated circuit.
