Pixel-matched holographic data storage with megabit pages

Abstract

Digital data-page holograms consisting of 1024×1024 arrays of binary pixels have been stored and subsequently retrieved with an optical exposure consistent with a data rate 1 Gbit/s. Each input pixel was precisely registered with a single detector pixel, and a raw bit-error rate as low as 2.4×10-6 was demonstrated with global-threshold detection. To our knowledge, this is the first demonstration of the often-cited goal of holographic data storage of megabit data pages and a gigabit-per-second data rate.
