Abstract: The ability of control of flow of light is of central importance for modern technology. Photon, the particle of light, is a neutral particle. Thus, there is no natural gauge field that couples to photon. In this talk, we show that, in dynamically modulated photonic structures, the phase of the modulation corresponds to a gauge potential that couples to photons and breaks time-reversal symmetry for photon flow. By utilizing a modulated ring resonator structure that exhibits a synthetic frequency dimension, we experimentally demonstrate the observation of signatures of such a gauge potential in terms of a quantum Hall effect for light. Moreover, we experimentally demonstrate that a non-Abelian gauge field can be achieved in such modulated ring resonator structures. Our work highlights significant richness in time-modulated photonic structures for controlling the flow of light.
