Spatially regular single photon emitters coupled via multifunctional collective Mie resonance of all dielectric metastructures: A new paradigm for on-chip integrated scalable quantum optical circuits
Abstract
Providing platforms that can encode information and do computation in quantum manner can overcome the limitation of current computation, information processing and communication systems. Single photon is one of the prominent candidates as information carrier for quantum information processing. The objective of this research is to explore the on-chip integration of co-designed quantum-dot photon emitters with subwavelength sized dielectric building block (DBB) arrays to actively manipulate (enhance emission rate, guide, focus, and filter) light at both classical and quantum level. The research will include: (1) modeling and simulation of the Mie modes of the DBBs to guide the design of dielectric metastructures that can manipulate (enhance emission rate, guide, focus, and filter) light; (2) developing protocols for fabricating DBB based metastructures in a planar membrane; (3) characterizing DBB light manipulating functions, and (4) characterizing the various QD arrays, including their single photon emission characteristics, photon coherence and interference. 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) metastructure network will be created in co-planar architectures designed to enhance QD emission and guide the emitted photons. The created QD emitters and DBB 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 DBB network. The QD arrays and the DBB network 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; far-field and near field scattering of DBBs for study Mie mode; and temperature and incident power dependent time-integrated photoluminescence and time-resolved photoluminescence for QD optical quality. Single photon emission behavior of the QD and interference of photons from the QDs will be examined respectively using appropriate Hanbury-Brown and Twiss instrumentation, Michelson interferometer and Hong-Ou-Mandel instrumentation. The major goal of the research is to explore and assess integration of DBB based networks with quantum dot single photon emitters as a new approach to realizing on-chip integrated optical quantum information processing systems.
