论文摘要
最近在非线性光学网格晶格中观察到了类似超流体行为的特征，其中在一对耦合的光纤环中传播的光脉冲的到达时间被解释为合成的空间维度。在这里，我们在这种光学网格晶格中发展了一般的光流体理论。一方面，该理论为实验观察的分析和数值解释提供了一个坚实的框架。另一方面，它预计我们的设置的特定时空周期性几何形状产生了新的物理效应。我们的工作为全面的光学网格晶格系统的全面开发开辟了道路，作为在新型构型中光流体研究中流体动力学现象研究的有前途的平台。
Signatures of superfluid-like behaviour have recently been observed experimentally in a nonlinear optical mesh lattice, where the arrival time of optical pulses propagating in a pair of coupled optical fiber loops is interpreted as a synthetic spatial dimension. Here, we develop a general theory of the fluid of light in such optical mesh lattices. On the one hand, this theory provides a solid framework for an analytical and numerical interpretation of the experimental observations. On the other hand it anticipates new physical effects stemming from the specific spatio-temporally periodic geometry of our set-up. Our work opens the way towards the full exploitation of optical mesh lattices system as a promising platform for studies of hydrodynamics phenomena in fluids of light in novel configurations.
