Abstract

Fundamental studies of the interaction of chiral light with chiral matter are important for the development of techniques that allow handedness-selective optical detection of chiral organic molecules. One approach to achieve this goal is the creation of a Fabry-Pérot cavity that supports eigenmodes with a desired electromagnetic handedness. We theoretically study chiral Fabry-Pérot cavities with mirrors comprising twisted one-dimensional photonic crystal slabs or homogeneous anisotropic layers. We demonstrate that such cavities support modes of both handednesses due to chiral morphology of the entire structure, set by the twist angle between the optical axes of the upper and lower mirrors. The developed chiral Fabry-Pérot cavities can be tuned to any distance between the mirrors by properly twisting them, making such systems a prospective platform for the coupling of chiral light with chiral matter.

Sergey Dyakov graduated from Faculty of Physics, Moscow State University in 2008. In 2012 he defended his Ph.D. thesis in Trinity College Dublin and joined KTH Royal Institute of Technology, Stockholm, Sweden, where he was working as a postdoctoral researcher for two years. After that, he joined Skolkovo Institute of Science and Technology. In 2022, Sergey Dyakov received an academic degree of Sc.D. in physics. Sergey Dyakov's research interests are focused on deepening our understanding of light-matter interaction for the design and development of new optical systems for their application in various fields of science and technology from fundamental physics to biology.
