High Capacity Data Storage Inspired from Lippmann Interference Photography

Abstract : Lippmann interference architectures are alternatives to holographic memories for high capacity data storage. In these systems, the image beam carrying the information data interferes with its reflection onto a mirror: no external reference beam is required. We implemented such a page‐oriented architecture using wavelength multiplexing and we report results obtained in a photopolymer material. We will also discuss the main advantages/drawbacks of such architectures compared to more conventional holographic arrangements.
