Optical computer routes light through multi-pass loop of optical elements, similar to how light bounces seemingly infinitely between mirrors

"loop allows light to build up complex relationships naturally over repeated passes, using standard LCD/ LED components... passive or low-power optics drastically reduces heat/ energy... photons do not interact with one another, allowing multiple signals to pass through simultaneously at speed of light... uses abundant/ cheaper materials... edge computing enables smaller, more efficient advanced AI to run on drones, medical sensors, cars without needing cloud connection or draining batteries"
