摘　　要：Within optical microresonators,the Kerr interaction of photons can lead to symmetry breaking of optical modes.In a ring resonator,this leads to the interesting effect that light preferably circulates in one direction or in one polarization state.Applications of this effect range from chip-integrated optical diodes to nonlinear polarization controllers and optical gyroscopes.In this work,we study Kerr-nonlinearity-induced symmetry breaking of light states in coupled resonator optical waveguides(CROWs).We discover,to our knowledge,a new type of controllable symmetry breaking that leads to emerging patterns of dark and bright resonators within the chains.Beyond stationary symmetry broken states,we observe Kerr-effect-induced homogeneous periodic oscillations,switching,and chaotic fluctuations of circulating powers in the resonators.Our findings are of interest for controlled multiplexing of light in photonic integrated circuits,neuromorphic computing,topological photonics,and soliton frequency combs in coupled resonators.
