论文摘要
腔通过提供促进光 - 物质相互作用的能量的时空限制，在光学物理学中起着基本作用。它们通常在各种设置中使用，从激光到光谱过滤器，到非线性波浪混合器和调节器。尽管它们的共振属性使它们适合感测，但在许多应用中，例如在激光器中，希望减轻其灵敏度，以使设备对扰动更具弹性。沿着这些路线，有几份有关使用拓扑物理学概念来设计激光阵列的一些报道，这些阵列本质上更健壮。在这里，我们基于Majorana Bound State提供了一类新的拓扑空腔，这些洞穴提供了独特的缩放特征以及非分级单模行为。这些空腔可能会导致一个新的激光和激光阵列家族，这些阵列可用于缺陷，制造缺陷和外部扰动。
Cavities play a fundamental role in optical physics by providing spatio-temporal confinement of energy that facilitates light-matter interactions. They are routinely utilized in a variety of settings, ranging from lasers to spectral filters, to nonlinear wave mixers, and modulators. While their resonant properties make them suitable for sensing, in many applications, like in lasers, it is desired to alleviate their sensitivity in order to make a device more resilient to perturbations. Along these lines there have been several recent reports of using concepts from topological physics in order to design laser arrays that are inherently more robust. Here, we present a new class of topological cavities based on Majorana bound states that provide unique scaling features as well as non-degenerate single-mode behaviors. These cavities may lead to a new family of lasers and laser arrays that are robust to defects, fabrication imperfections, and external perturbations.
