Performing optical logic operations by a diffractive neural network

(Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, Chinese Academy) Optical logic operations, as the basis of optical computing, hold huge potentials to many applications such as cryptographically secured wireless communication and real-time wavefront-shaping. To this goal, Scientist in China demonstrated a general framework for all optical logic operations by a compound Huygens' metasurface enacted diffractive neural network, and verify it in a microwave experi...
