Unlimited Lifetime
—5 Dimensional Data Storage in Nanostructured Glass
2015
通过超快激光，一个2.5 MB的数字视频文件被成功记录在纳米五维数据储存玻璃中，产生了仅为1的10分之1秒，但却具有极强脉冲的光。文件被写入5层被分为5微米（1 ⁄ 1000000）的纳米点中。自组织纳米结构改变了光穿过玻璃的方式以及它的偏振，然后可以通过同时使用光学显微镜和偏光镜进行读取，原理类似于偏光太阳镜。
A 2.5 MB digital copy of a video file was successfully recorded in 5D using ultrafast laser, producing extremely short (one tenth of trillionth of a second) and intense pulses (ten millions of billions) of light. The file is written in 5 layers of nanostructured dots separated by five micrometres (one millionth of a metre). The self-assembled nanostructures change the way light travels through glass, modifying polarisation of light that can then be read by combination of optical microscope and a polariser, similar to that found in Polaroid sunglasses.

这一物理光学小组由Peter Kazansky教授带领，课题组目前的研究活动集中在对光学、量子以及物理电子学潜在巨大影响的探索和研究。当前的研究包括光子结构的三维直写，这一研究将产生全新的作品，为集成光学领域提供更多待望已久的可能，比如开关、微光学元件、嵌入式衍射光学阵列互连、光束合成等等。
The Physical Optics Group is led by Professor Peter Kazansky. Research activities in the group are focused on adventurous and potentially high impact research in optics, quantum and physical electronics. Current research includes femtosecond direct writing of 3D photonic structures. Photonic structures patterned in three-dimensions providing entirely new functionalities offer tantalizing possibilities in the field of integrated optics, e.g. switches and compact delay lines and micro-optics, e.g. embedded diffractive optics arrays for interconnection and synthesis of light beams.
