Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules
Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment, this is accomplished by exploiting photochromic molecules for monitoring the presence or absence of photons of particular wavelengths that represent the logic variables.
