Switchable holographic gratings formed in polymer-dispersed liquid-crystal cells by use of a He-Ne laser.
We report on the formation of switchable holographic transmission gratings in polymer-dispersed liquid-crystal cells by use of the 633-nm wavelength of a He-Ne laser. We present results for the structure, diffraction efficiency, and switching characteristics of the gratings.
