Optical chiral properties in a large resonant hybrid photonic cluster

Abstract

Optical chiral properties of a resonant hybrid photonic crystal (RHPC) are computed taking into account spin-orbit effect due to light-hole excitons perfectly confined in 2D quantum wells. The trends of the optical activity, expressed as a ratio between the absorption intensities of the z and xy light-hole polaritons, are obtained by computing the optical response in a rather large N-cluster of elementary cells (N= 34) and for exciton energy, in resonance with a stationery inflection point (SIP). High values of spin-orbit interaction (0.7 eV A) produce strong distortions of the optical activity polar curves that, differently, becomes rather isotropic if the experimental value (0.14 eV A) is used.
