Recent advances in holographic data storage in SBN

摘要

Abstract: In this paper we discuss recent advances in holographic data storage using ferroelectric SBN as the recording medium. A novel optical architecture involving an array of SBN fibers is discussed that allows 2 - 3 orders of magnitude faster access times than for conventional magnetic data storage devices of Gbyte size. To realize this potential we are studying fundamental materials issues related to SBN fiber growth and photorefractive processes underlying prolonged readout in SBN. !9
