Photorefractive materials are capable of reversibly changing their index of refraction upon illumination. That property allows them to dynamically record holograms, which is a key …
Undoubtedly the applications of polymers are rapidly evolving. Technology is continually changing and quickly advancing as polymers are needed to solve a variety of day-to-day …
A multifunctional hybrid photorefractive nanocomposite has been developed (see Figure); it consists of a carbazole-based photoconducting matrix, a nonlinear chromophore, and …
Individual nanosecond pulses at 532 nm are applied to record gratings in photorefractive composite. At 4 mJ∕ cm 2 illumination, maximum diffraction efficiencies of 56% have been …

Photorefractive composites derived from photoconducting polymers offer the advantage of dynamically recording holograms without the need for processing of any kind. Thus, they are …
Photorefractive materials can be used to record and erase holograms many times without the need for chemical processing. This places photorefractive materials at the cutting edge …
A photorefractive polymer composite sensitized at 1550 nm through direct two-photon absorption has been developed. We show an external diffraction efficiency of 3% in four …
The development of a high-performance photorefractive polymer composite operating at 1550 nm is reported. We show 40% internal diffraction efficiency with response time of 35 …
