We describe the design and construction of ultrahigh capacity three-dimensional, 3D, optical storage devices that operate by two-photon absorption. The molecular systems and their properties that are used as two photon media for writing and one photon for accessing the stored information within the volume of the device are presented in some detail and the nonlinear two-photon absorption mechanism is briefly visited. The optical system and its components, which facilitated writing and reading, are also described and the bit density, bit error rate, store and access speeds, cycle times, and stability of the materials under various experimental conditions are also topics addressed in this review. The first ever storage of terabyte data in a removable storage disk is described in detail.
我们描述了通过双光子吸收作用工作的超高容量三维（3D）光学存储设备的设计和构建。文中详细介绍了用作双光子介质进行写入以及单光子用于访问设备体积内存储信息的分子系统及其特性，并简要讨论了非线性双光子吸收机制。还描述了便于写入和读取的光学系统及其组件，并且在各种实验条件下还讨论了材料的比特密度、误码率、存储和访问速度、循环时间和稳定性等主题。详细描述了首次在可移动存储磁盘中存储兆兆字节数据的情况。
