"directly classify complex information harnessing light from single optical fiber (energy-efficient) AI learning without additional intelligent software... perform neural networks' tasks at light speed... mixing of light frequencies, data encoded onto ultrashort light pulse color channels undergoing combinations, amplifications, or attenuations... specific color output might indicate visible objects in images or signs of illness in a voice... pixel values converted into intensities primary colors, within fiber,  primary colors blend"
