Abstract

We investigate theoretically the polarization properties of the quantum dot´s (QDs) optical emission from a chiral photonic crystal nanostructure made of achiral materials in the absence of external magnetic field at room temperature. Recently, similar nanostructures were investigated and the circular polarization degree of QDs emission as high as 26% (for a planar semiconductor waveguide with chiral spatially-modulated upper part [1]) and 81% (for a microcavity with chirally half-etched top mirror [2]) was experimentally achieved.
