Chiral Quantum Optics and Optical Nonreciprocity Based on Susceptibility‐Momentum Locking
Lei Tang, Jiang-Shan Tang, Keyu Xia
Abstract
Abstract The progress in chiral light–matter interaction in the quantum regime leads to emergence of chiral quantum optics and quantum nonreciprocity. Spin‐momentum locking is at the heart of chiral quantum optics. In this short review, the basic knowledge of optical nonreciprocity and susceptibility‐momentum locking (SML) is introduced as a novel mechanism for conducting chiral quantum optics. Various approaches achieving optical nonreciprocity based on SML are also reviewed. A perspective regarding the challenges in this direction will also be provided.
