我们从理论上表明，多端口光子晶格模拟驱动量子谐振子产生Aharonov-Anandan几何相位，这是成比例的相关的动态相位，而不管初始状态。因此，可以直接测量非绝热几何相位，而不需要复杂的设置来去除动态相位。此外，我们提出了观察这样的几何相位在多端口光子晶格通过集成干涉。我们的工作为基于调制的拓扑光子学集成光子平台的潜在发展提供了见解。
We theoretically show that multiport photonic lattices emulating driven quantum harmonic oscillators give rise to Aharonov–Anandan geometric phase, which is proportional to the associated dynamic phase irrespective of the initial state. Consequently, the non-adiabatic geometric phase can be directly measured without the need of complex setups to remove the dynamic phase. Further, we propose the observation of such geometric phases in multiport photonic lattices via integrated interferometry. Our work provides insights into the potential development of integrated photonic platforms for modulation-based topological photonics.
