Experimental demonstration of spatiotemporal analog computation in ultrafast optics

Light: Science & Applications
Abstract It is intractable to perform information processing and computation on single ultrafast optical pulses, within picoseconds or even femtoseconds. Here, we experimentally demonstrate an optical spatiotemporal differentiator, a mirror-symmetry-breaking dielectric metagrating, which performs analog computations of both spatial ...
