Description
We investigate the mechanism of chiral light-matter interactions for molecular ensembles embedded inside an optical Fabry-Perot cavity. We show how to describe and compute chiroptical properties of such cavities using classical methods based on transfert matrix approaches taking into account the mirror scattering properties. Then we propose and analyse a simplified microscopic model of standard cavity and unveil the key-role of dimensionality in describing its polaritonic spectral properties. For a quasi 2D-layer configuration, we show that the interplay between molecular chirality and spatial dispersion of the cavity-modes, results in a gyrotropic coupling at the origin of a differential shift in polaritonic energy spectra. We provide finally physical analogues of such effects by analyzing the classical Newtonian motion of a fictitious Foucault pendulum. Open questions and perspectives in this field will be enlighten.
