Fano resonance is a universal phenomenon observed in many areas where wave propagation and interference are possible. Fano resonance arises from the interference of broad and narrow spectra of radiation and becomes an important tool for many applications in the physical, chemical, and biological sciences. At the beginning of this paper, we consider Fano resonances in individual particles, primarily of spherical and cylindrical shapes, and discuss their connection with the physics of bound states in the continuum that determine the high quality factors of resonators. Further, we discuss two areas in which structures with Fano resonances have already found or will find real application in the nearest future—sensors and lasers. The penultimate section concerns our future, which will be associated with the complete replacement of electronic processing, transmission, and storage of information with optical devices as many hope. It is believed that this sophisticated goal can be achieved with devices that implement the slow-light regime associated with the phenomenon of electromagnetically induced transparency, which can be considered as a special case of Fano resonance. The review completes with one more promising topic related to quantum electrodynamics in structures with Fano cavities.

范诺共振应用

法诺共振是在波传播和干扰可能存在的许多领域中观察到的普遍现象。法诺共振产生于宽谱和窄谱辐射的干扰，并成为物理、化学和生物科学中许多应用的重要工具。在本文的开头，我们考虑了单个粒子（主要是球形和圆柱形）中的 Fano 共振，并讨论了它们与确定共振器高质量因子的连续介质中束缚态物理学的联系。此外，我们讨论了具有 Fano 共振的结构已经发现或将在不久的将来真正应用的两个领域——传感器和激光器。倒数第二部分涉及我们的未来，这将与电子处理的完全替代有关，正如许多人所希望的那样，使用光学设备传输和存储信息。人们相信，这个复杂的目标可以通过实现与电磁感应透明现象相关的慢光状态的设备来实现，这可以被认为是 Fano 共振的一个特例。该评论以一个与 Fano 腔结构中的量子电动力学相关的更有前景的主题结束。
