Programmable photonic chip could unlock light-speed optical computing

We want faster and faster computers, and light is the fastest thing in the universe. Therefore, light-based computers should be awesome. Right? Not quite. Computing isn't always about data arriving fast. Sometimes it's about arriving on cue. We have learned how to force light to calm down, but today’s hardware matches a specific design to a specific speed. But how do we command light to arrive faster or slower, using the same hardware?Continue ReadingCategory: Computing, Consumer Tech, TechnologyTags: Seoul National University, Light, Optical Computing, Photonics
