Abstract

Non-reciprocal devices such as circulators and isolators are indispensable to classical and quantum information processing in photonic integrated circuits. But integrating conventional optical non-reciprocal devices, which employ the magneto-optical Faraday effect, is technically challenging because of material incompatibilities and the large footprint of device designs. In 2016, we experimentally demonstrated non-magnetic non-reciprocity using optomechanical interactions in a whispering-gallery microresonator.
