我们报道了一种记录介质，在这种介质中，可以利用双光子过程光制造三维纳米结构用于多层光存储器。通过在介质中制造结构，我们可以控制记录比特的形状，实际上，控制它们的空间频率分布。我们成功地记录了在任何特定平面上间隔为0.5μm，连续层之间间隔为2.0μm的比特。因此，实现了2.0Tbits scincm ~ 3的存储密度。
We report a recording medium in which a three-dimensional nanoscale structure can be photofabricated for multilayered optical memory using a two-photon process. By fabricating the structures in the medium, we can control the shape of recorded bits and, in effect, their spatial frequency distribution. We succeeded in recording bits with a 0.5μm interval in any particular plane and 2.0μm interval between successive layers. Thus, storage density of 2.0Tbits∕cm3 is achieved.
