Phenanthrenequinone-doped poly(methyl methacrylate) photopolymer bulk for volume holographic data storage.
We present the design and fabrication of a phenanthrenequinone-doped poly(methyl methacrylate) photopolymer material. Large blocks of samples were made, and the material showed negligible shrinkage after optical exposures. We recorded and reconstructed 250 holograms at a single spot, using a 1-cm(3) block.
متن کاملPerformance improvement of high thickness photopolymers for holographic data storage applications
We use 4,4’ azo-bis-(4-cyanopentanoic acid) as chain transfer agent in a photopolymer with triethanolamine/yellowish eosin as initiator system. It is possible to work in a particular conditions to get a chain transfer effect minimizing the decomposition of 4,4’ azo-bis-(4-cyanopentanoic acid) by the sensitized dye. The improved photopolymer has a low scattering due to the low molecular weight o...
متن کاملCharacterization of phenanthrenequinone-doped poly(methyl methacrylate) for holographic memory.
The holographic recording characteristics of phenanthrenequinone- (PQ-) doped poly(methyl methacrylate) are investigated. The exposure sensitivity is characterized for single-hologram recording, and the M/# is measured for samples as thick as 3 mm. Optically induced birefringence is observed in this material.
متن کاملHolographic Data Storage
Introduction With its omnipresent computers, all connected via the Internet, the Information Age has led to an explosion of information available to users. The decreasing cost of storing data, and the increasing storage capacities of the same small device footprint, have been key enablers of this revolution. While current storage needs are being met, storage technologies must continue to improv...
