  • Abstract
    We fabricated photonic crystal nanocavities containing single SiGe QDs deterministically aligned to the antinodes of a cavity mode. Cavity coupling drastically enhances the vertical QD emission and allows, for the first time, the optical characterization of a single SiGe QD. For low excitation intensities, a single exponential PL decay with a time constant of 22ns at T=10K is observed for such a coupled QD-PhC-cavity system.
