Abstract

Fundamental studies of the interaction of chiral light with chiral matter are important, especially for the development of methods that allow selective optical detection of chiral organic molecules. One approach to achieve this goal is to develop a Fabry-Perot resonator that supports eigenmodes with desired electromagnetic handedness which interact differently with the left and right molecular enantiomers. In this study, we theoretically investigate chiral Fabry-Perot resonators with mirrors formed by one-dimensional photonic crystal slabs. We show that the electromagnetic field of the eigenmodes of such resonator can reach the maximum chirality and the intensity distribution is homogeneous without zeros. The one-dimensional photonic crystal mirrors of such a Fabry-Perot resonator have a much simpler geometry than existing solutions, and the rotational degree of freedom allows for fine tuning.
