Abstract
We report electrical switching of the diffraction efficiency in volume Bragg gratings written holographically in polymer-dispersed liquid cr ystals (PDLCs). Scanning electron microscopy confirms the volume natur e of the gratings and shows that they consist of periodic PDLC planes. The diffraction efficiency can be switched from a high value (approxi mately 50%) to a value near zero at fields approximately 11 V/mum.
