摘要：

We present thermal features of holographic gratings recorded in near infrared sensitive polymer dispersed liquid crystal films. Experimental results indicate that the diffraction efficiency of our gratings can be smoothly controlled by monitoring the sample's temperature. Diffraction efficiencies versus temperature for both s- and p-polarized probe and transmitted probe's polarization are studied and qualitative explanations are provided.
