Title of Paper: A Volumetric Memory Device based on Photo-Chromatic Compounds
Principal Author: Dr. Tom Milster
Abstract: For space applications, semiconductor memories that are radiation hardened and consume low power are currently being used at cost of $5000/Gbit. The three-dimensional (3D) optical memory is a revolutionary technology that has the benefits of lower cost (tens of dollars/Gbit), order of magnitude smaller size and mass, and lower risk. We report on investigation and characterization of a three-dimensional (3D) and volumetric optical memory device based on a new class of light-absorbing (photo-chromic) compounds that, when pulsed with lasers, absorb photons two at a time and can trigger chemical and physical changes (such as fluorescence) with micrometer-sized resolution in three dimensions.
