A POLYSILOXANE-BASED PHOTOREFRACTIVE POLYMER WITH HIGH OPTICAL GAIN AND DIFFRACTION EFFICIENCY

Photorefractive polymers have great potential in applications such as all-optical switching and optical communication. Here, new charge-tran sporting polymers are presented based on a polysiloxane backbone with pendant carbazole groups, which provide both transport and room-temper ature poling properties without the need for additional plasticizing c omponents. A quantitative evaluation of the phase behavior of holograp hic gratings based on the new materials is also presented.
