Recently, a new class of light modulators, based on PDLC systems have been reported(1,2). Here, we present a Polymer Dispersed Chiral Nematic (PDCN) utilizing the linear electro-optic effect in chiral nematics with uniformly aligned helix under an electric field, applied normally to the helix axis(3). A fairly good linear response has been detected in such PDCN films, containing a chiral nematic mixture 6415 L (Hoffmann La Roche), possessing a short pitch (about 0.3 mu m), temperature independent in wide temperature interval (0 degrees C - 50 degrees C). Response time of about 100 mu s has been measured.
