We demonstrate a synthetic Hall effect for light, using an acousto-optically modulated nanophotonic resonator chain. To produce this effect, we simultaneously generate the required synthetic electric field using temporal modulation and the required synthetic magnetic field using spatial modulation of the resonator chain. We show how the combination of these synthetic fields transverse to the direction of light propagation can be used to produce non-reciprocal optical transmission, as a basis for new photonic and topological devices.

通过光子的合成霍尔效应实现片上光学不可逆性

我们演示了使用声光调制的纳米光子谐振器链的光的合成霍尔效应。为了产生这种效果，我们同时使用时间调制来生成所需的合成电场，并使用谐振器链的空间调制来生成所需的合成磁场。我们展示了如何将这些垂直于光传播方向的合成场的组合用于产生不可逆的光传输，作为新的光子和拓扑设备的基础。
