模拟重力使在实验室中研究弯曲时空上的场成为可能。在许多实验平台上，已经观察到视界或遍历区域的放大。在这里，我们演示了如何在极化子微腔中光学生成缺陷，从而能够创建一维和二维跨音速流体流动。我们表明，这种高度可调的方法允许视界的创建。此外，我们提出了一个类似于水波浴缸漩涡的旋转几何形状。这些实验为观察光流体中霍金效应、彭罗斯效应和泽尔德维奇效应的受激放大和自发放大提供了可能。这篇文章是讨论会议“下一代模拟重力实验”的一部分。
Analogue gravity enables the study of fields on curved space-times in the laboratory. There are numerous experimental platforms in which amplification at the event horizon or the ergoregion has been observed. Here, we demonstrate how optically generating a defect in a polariton microcavity enables the creation of one- and two-dimensional, transsonic fluid flows. We show that this highly tuneable method permits the creation of horizons. Furthermore, we present a rotating geometry akin to the water-wave bathtub vortex. These experiments usher in the possibility of observing stimulated as well as spontaneous amplification by the Hawking, Penrose and Zeld'ovich effects in fluids of light. This article is part of a discussion meeting issue 'The next generation of analogue gravity experiments'.
