High-transfer-rate high-capacity holographic disk data-storage system

TLDR

The study presents a high‑data‑rate, high‑capacity digital holographic storage disk system. The system uses high‑resolution short‑focal‑length optics and correlation‑shift multiplexing in photopolymer disk media, with custom electronics decoding holographic channels at 1‑Gbit/s. The system achieved a sustained optical data‑transfer rate of 10 Gbits/s.

Abstract

We describe the design and implementation of a high-data-rate high-capacity digital holographic storage disk system. Various system design trade-offs that affect density and data-rate performance are described and analyzed. In the demonstration system that we describe, high-density holographic recording is achieved by use of high-resolution short-focal-length optics and correlation shift multiplexing in photopolymer disk media. Holographic channel decoding at a 1-Gbit/s data rate is performed by custom-built electronic hardware. A benchmark sustained optical data-transfer rate of 10 Gbits/s has been successfully demonstrated.
