Поляризационные и спектрально-пространственные свойства излучения в хиральных полупроводниковых наноструктурах
A detailed study of the degree of circular polarization and the angular dependence of the emission spectra of
an array of InAs quantum dots embedded in GaAs photonic nanostructures with chiral symmetry in the
absence of an external magnetic field is carried out. A strong angular dependence of the spectra and the degree
of circular polarization of radiation from quantum dots, as well as a significant effect of the lattice period of
the photonic crystal on the radiation characteristics, is observed. The dispersion of photonic modes near the
and Bragg resonances is investigated in detail. The experimentally observed polarization,
spectral, and angular characteristics of the quantum-dot emission are explained in the framework of a theory
describing radiative processes in chiral photonic nanostructures.
