Abstract
The properties of a space-time light modulator comprising an a-Si:H based p -i-n diode and a nematic liquid crystal layer were studied using a holograp hic technique. Under certain conditions, an asymmetry of the diffraction ef ficiency in the +1 and -1 diffraction orders was observed. The maximum diff raction efficiency in one of these orders may reach up to 52%, which is a r ecord value for devices of this type. (C) 2001 MAIK "Nauka/Interperiodica".
