Abstract:

In this project, we 1 demonstrated colloidal Quantum Dot QD based vertical-cavity surface emitting lasers VCSELs with record low thresholds, 2 engineered the local density of optical states LDOS in 1D waveguides to control the emission of randomly oriented QDs, 3 demonstrated silica cladding of commercial QDs, and thus broadened the range of QD sources suitable for on-chip integration using electrostatic self-assembly methods, 4 demonstrated a robust, reusable platform of alumina templates for the precise placement of single colloidal QDs, 5 built a custom scanning confocal microscope setup capable of performing large-scale characterization of the lifetime and g2 autocorrelation of individual QD emission in self-assembled arrays, and 6 integrated colloidal QDs in dielectric waveguides and near resonant nanostructures.
