Co-Designed Dielectric Nanoparticle Optical Metamaterial - Active Device Integrated Photonic Systems
Abstract
The objective of this research is to explore the on-chip integration of quantum-dot photon emitters with dielectric nanostructure arrays that can actively manipulate (enhance emission rate, guide, focus, and filter) light. The objective of this research is to explore the on-chip integration of co-designed quantum-dot photon emitters with nanoscale dielectric building block (NDBB) arrays to actively manipulate (enhance emission rate, guide, focus, and filter) light. This research will include: (1) modeling and simulation of the Mie scattering by NDBBs to guide the design of dielectric metamaterials that can focus and steer photons; (2) developing protocols for fabricating ordered quantum dot array and NDBB network in planar 2D and 1D arrays; and (3) characterizing (a) the various QD arrays, including their single photon emisson characteristics, and (b) NDBB networks. The GaAs/InGaAs/AlGaAs QD arrays will be created via molecular beam epitaxial self-organized growth on the tops of GaAs nano-mesas. Dielectric (such as GaAs, Si, TiO2) nanostructure network will be created in co-planar architectures designed to enhance QD emission and guide the emitted photons. The created QD emitters and NDBB based networks will be co-designed to match both spectrally and spatially. A unique all-UHV interconnected growth, processing, and characterization system is in place that will facilitate the integration and testing of the prototype QD array and NDBB network. The QD arrays, NDBB network, and the integrated photonic systems will be characterized utilizing a variety of techniques that will include: in-situ RHEED (reflection high-energy electron diffraction) for guiding QD synthesis; AFM (atomic force microscopy) and SEM (scanning electron microcopy) for shape and surface morphology; spectroscopic ellipsometry for refractive index; and temperature and incident power dependent time-integrated photoluminescence and time-resolved photoluminescence for QD optical quality. Single photon emission behavior of the QDs will be examined using appropriate Hanbury-Brown and Twiss instrumentation. The major goal of the research is to explore and assess integration of NDBB based networks with quantum dot single photon emitters as a new approach to realizing on-chip integrated optical quantum information processing systems.
