Nonvolatile photorefractive spectral holography.
We demonstrate nonvolatile storage of femtosecond pulses in a photorefractive LiNbO(3) crystal with recording and readout of spectral holograms at wavelengths of 460 and 920 nm, respectively. No degradation was observed after 24 h of continuous readout. We also show that we can realize the time-lens effect with our system by appropriately setting the ratio of the recording and the reconstructio...
متن کاملMicrowave Signal Processing with Photorefractive Dynamic Holography
Have you ever found yourself listening to the music playing from the closest stereo rather than to the bromidic (uninspiring) person speaking to you? Your ears receive information from two sources but your brain listens to only one. What if your cell phone could distinguish among signals sharing the same bandwidth too? There would be no “full” channels to stop you from placing or receiving a ca...
متن کاملDark decay of holograms in photorefractive polymers
The decay of holograms stored in photorefractive polymer composites based on poly~N-vinyl-carbazole! with and without extrinsic deep traps is investigated. The photorefractive phase shift is identified as one of the key parameters determining the dark decay dynamics. This has important implications for all kinds of photorefractive imaging applications including holographic data storage. A trade...
متن کاملPhotorefractive Polymers and Their Applications in Photonics
The demand for holographic recording materials has been ever increasing for the past few decades. Photorefractive materials have been studied extensively as candidate recording media. They offer high index modulation with reversible recording that make them very attractive for applications such as threedimensional holographic displays, adaptive optics, optical data storage and medical optics. R...
متن کاملHigh-speed wide-field coherence-gated imaging via photorefractive holography with photorefractive multiple quantum well devices
The parallel pixel acquisition inherent in wide-field coherence-gated imaging techniques offers the possibility of high-frame-rate imaging and volumetric imaging, including through scattering media. We discuss photorefractive holography using sensitive, dynamic photorefractive multiple quantum well (PRQW) films as a promising approach and, after reviewing the factors that determine the sensitiv...
