Abstract

Holographic data storage has emerged as one of the promising technologies to satisfy the demands of high-density data storage and retrieval. Here we propose the usage of Azo functionalized copolymer as the storage material and structured light as data encoding technique to realize high-density data storage and retrieval. A hybrid polarization-angle-depth multiplexing technique us employed to further increase the data density without crosstalk. The material also exhibits long retention time and faster re-writability and thereby possesses the potential to satisfy the demands of next generation data storage technologies.
