Design and implementation of a page-oriented "holographic" memory based on a Lippmann architecture.
Optical data storage inspired by Lippmann interference color photography was proposed a long time ago as an alternative to holographic memories. Very high capacities were predicted for a page-oriented approach with wavelength multiplexing, but, up to now, such an architecture has never been implemented. Based on simple conception rules, we build such a page-oriented Lippmann data storage system. Submicrometer resolved data pages recorded in thick materials are evidenced by the experimental results.
