Abstract

High-Q Fano resonances are demonstrated, as well as effects similar to electromagnetically induced transparency arising in a curved Fabry-Perot waveguide resonator with variable-reflection mirrors. It is shown that these effects arise as a result of coupling the fundamental mode of the bent waveguide core with whispering gallery cladding modes. An influence of the main geometrical parameters of the resonator on the resonance features in its reflection and transmission spectra is studied. The results obtained can be used in the creation of new functional elements of photonics based on curved waveguides, in particular, highly sensitive portable refractometers for bio- and chemosensory systems, as well as optical sensors of mechanical effects.

具有空间可变反射率反射镜的弯曲波导谐振腔中的高q可调谐法诺共振

高q范诺共振被证明，以及类似于电磁诱导透明产生的效应，弯曲法布里-珀罗波导谐振器与可变反射镜。结果表明，这些效应的产生是由于弯曲波导核心的基模与低语廊包层模式耦合的结果。研究了谐振腔主要几何参数对其反射光谱和透射光谱共振特性的影响。所得结果可用于基于弯曲波导的光子学新功能元件的创建，特别是用于生物和化学传感系统的高灵敏度便携式折光计，以及机械效应光学传感器。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
