R&D: Miniaturization for Dual-Beam Super-Resolution Optical Storage System With High Capacities

Specially designed lens head offers distinct performance of chromatic aberration-free design with adaptability to multiple dual-beam combinations.

IEEE Xplore has published, in 2018 Asia-Pacific Magnetic Recording Conference (APMRC), an article written by Xu Chen, Binbin Yu, Jing Wen, Shiliang Liu, and Dawei Zhang, University of Shanghai for Science and Technology, Engineering Research Center of Optical Instrument and System, Ministry of Education and Shanghai Key Lab of Modern Optical System, No. 516 JunGong Road, Shanghai, 200093, China.

Abstract: A minimized optical lens head for dual-beam super-resolution optical storage system which is based on Stimulated Emission Depletion (STED)-like process with Petabyte data capacity is proposed. The whole bulky optical path is simplified to a customized metasurface with a diameter of 50µm, which generates a focused Gaussian beam and a donut beam overlapped perfectly in space. The specially designed lens head offers a distinct performance of chromatic aberration-free design with adaptability to multiple dual-beam combinations.
