Wavelength-multiplexed memory based on a Lippmann architecture

It is well recognized that holographic data storage may represent the next generation of optical data storage. Unlike DVDs and other optical discs in which information is stored in a plane, holographic storage technologies have a volumetric memory. Among several configurations, the page-oriented architectures present great advantages, such as the high data rate that stems from their inherent parallelism. In this communication, we will report on this storage capacity, and also on the first implementation of this architecture, based on the Lippmann photographic process in which pages of data are stored with wavelength multiplexing.
