A multifunctional photorefractive material showing high optical gain and diffraction efficiency
The design and synthesis of a new photorefractive material by incorporation of an oligo(3-alkylthiophene) segment with a nonlinear optical chromophore is reported by the authors. They demonstrate the potential use of this material as an optical data storage and image processing medium. Studies of the formation dynamics of holographic gratings (the Figure shows a holographic image) reveal the fast response time of the material to optical signals.
