Dielectric thin-film color optical memory device and fabrication process

摘要: The DTF optical memory makes use of the property dielectric thin film interference to create multi-color pixels and serve as a multi-level device. fabrication device comprises deposited on substrate that is micro-milled utilizing focused ion beam (FIB) technology. Such micro-milling creates varying depth when exposed broad-band light source distinct colors caused by properties superposition reflected from broad band source, thus creating an effective may be detected using color CCD camera or photo-detector array. Accurate creation detection discrete allows accurate digital encoding direct storage image in format sub-micron pixel robustness operation under harsh environmental conditions, including high temperatures radiation.
