日本丰田工业大学与新技术事业团共同开发出光计算机用翻转型光双稳元件。 该元件开关速度为100ps,若将其作为存储元件用的话,其工作速度为高速半导体存储器的50倍。 该元件是采用掺杂了具有窄吸收光谱铒元素的铝、钇、石榴石晶体作为控制光透过量的滤光片。当半导体激光器注入电流达到一 Toyota University of Technology and the New Technology Group jointly developed a light computer flip type bistable components. The device switches at 100ps and, if used as a storage device, operates 50 times faster than high-speed semiconductor memory. This element uses an aluminum, yttrium, garnet crystal doped with a narrow absorption spectrum of erbium as a filter for controlling the amount of light transmitted. When the semiconductor laser injection current reaches one
