This Small Business Innovation Research Phase I project examines holographic data storage based on photorefractive recording materials as a promising approach to overcoming the present I/O bottleneck that exists between high-speed microprocessors and mass storage peripherals. Many of the needed optical systems components (SLMs, CCDS, and tunable diode-lasers) are now available with sufficient performance specifications; however, the lack of a suitable volume recording medium is the primary problem. The medium should possess high sensitivity, large dynamic range, and a reliable mechanism for nondestructive readout. No single material to date satisfies all of these important criteria. Com:One Devices, Inc., proposes to overcome this limitation by using novel doping schemes to provide optimized two-photon photorefractive recording. Evaluation of the dopants is based on detailed spectroscopic and photoconductivity measurements. This approach is designed to provide a viable two-photon recording material that will ultimately be used in a first-generation read-write mass storage demonstration device.

这个小型企业创新研究第一阶段项目研究了基于光折变记录材料的全息数据存储，作为克服目前存在于高速微处理器和大容量存储外设之间的 I/O 瓶颈的有前途的方法。许多所需的光学系统组件（SLM、CCDS 和可调谐二极管激光器）现在都具有足够的性能规格；然而，缺乏合适的卷记录介质是首要问题。该介质应具有高灵敏度、大动态范围和可靠的无损读出机制。迄今为止，还没有任何一种材料能够满足所有这些重要标准。 Com:One Devices, Inc. 提议通过使用新颖的掺杂方案来提供优化的双光子光折变记录来克服这一限制。掺杂剂的评估基于详细的光谱和光电导测量。这种方法旨在提供一种可行的双光子记录材料，最终将用于第一代读写大容量存储演示设备。
