- Аннотация: 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 hand-edness, which interacts differently with left and right molecular enantiomers. In this paper, we theoretically study chiral Fabry-Pérot cavities with mirrors comprising one-dimensional photonic crystal slabs made of van der Waals As2S3, a material with one of the highest known in-plane anisotropy. By utilizing the anisotropy degree of freedom provided by As2S3, we design Fabry-Pérot cavities with constitutional and configurational geometrical chiralities. We demonstrate that in cavities with constitutional chirality, electromagnetic modes of left or right handedness exist due to the chirality of both mirrors, often referred to as handedness preserving mirrors in the literature. At the same time, cavities with configurational chirality 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 non-chiral anisotropic mirrors. The developed chiral Fabry-Pérot cavities can be tuned to the technologically available distance between the mirrors by properly twisting them, making such systems a prospective platform for the coupling of chiral light with chiral matter.
