(Color online) Left: Scanning electron micrograph showing the photonic crystal cavity (a). Middle: Simulated electric field intensity of the (b) and (c) dipole modes in the asymmetric cavity. The measured factors are and 200, respectively.
(Color online) PbS quantum dot spectra: and 950 nm dot spectra taken on a bulk silicon wafer.
(Color online) Cavity resonances mapped out by quantum dots in PMMA. Top: Polarization dependence of modes confirming that they are and dipole modes. Bottom: Ex dipole mode measured at two orthogonal polarizations. Angles refer to analyzer positions.
