Abstract :
We have fabricated a nematic liquid crystal layer sandwiched between photoconducting polymeric layers (porph-vrin-doped PVK) and measured rea[-time selfld@raction signals for different applied voltages. The gratings recorded are easily switchable by means of laser beanis or applied voltage.
