Paper Abstract

Electron trapping (ET) materials are novel storage media developed by Quantex. The architecture of a three-dimensional stacked layer optical memory based on ET materials is reported in this paper. Two-dimensional page memories are individually stored in ET layers by properly imaging the page composer onto a specific layer with blue light. To read out data in a specific layer, a slice of IR beam is addressed into the ET layer from the side of the stacked layer media. The addressed ET thin film contains the IR read beam like a slab waveguide. The orange emission corresponding to written page memory at that layer is emitted as a result of the IR stimulation. System design considerations and preliminary experimental results are presented.
