Cavity-Free, Matrix-Addressable Quantum Dot Architecture for On-Chip Optical Switching

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.
