Abstract

We report the photorefractive properties of tetraphenyldiaminobiphenyl (TPD) based polymer composites that have been developed for single pulse laser operation at 532 nm. With an optimized composite, we demonstrate more than 50% diffraction efficiency using 4 mJ/cm² single shot writing and 633 nm continuous wave (cw) beam reading. The present devices showed a 300 μs fast response time. This reveals the potential for these polymer devices in applications which require fast writing and erasure. Since the writing pulse-width is in nanosecond time scale, the recording is totally insensitive to vibrations. These devices can also be used as a stepping stone to realize all-color holography since they are sensitive to both green (532nm) and red (633nm) wavelengths. The holograms can be written with either of these two wavelengths and can be read by the same wavelength or the other wavelength with high diffraction efficiency. This demonstrates that these devices have the advantage of performing two-color holography, a step closer to a dynamic full-color holographic recording medium.
