Abstract

Measurements are made of the spectra and degrees of circular polarization of radiation from single InAs quantum dots embedded in a planar GaAs waveguide of a semiconductor nanostructure, and an electrically pumped semiconductor laser based on an AlAs/AlGaAs microcavity with GaAs quantum wells in the active region. The upper layers of the microcavity are a square lattice of a photonic crystal with chiral symmetry.
