Three-dimensional optical memory based on transparent electron-tra

摘要

Abstract: Transparent electron trapping (ET) thin films are optical storage media recently developed by Quantex. A 3-D erasable optical memory based on stacked ET thin film layers is presented in this paper. The page memory is written by properly imaging the page composer onto a specific layer with blue laser light at 488 nm. To read out the memory on a specific layer, a slice of 1064 nm infrared (IR) beam is guided into the ET layer from the side of the stacked layer media. The orange emission (around 630 nm) corresponding to the written page memory at that layer is emitted as the result of the IR stimulation. The feasibility of this novel 3-D optical memory has been demonstrated by preliminary experiments.!10
