High resolution studies of single photon emission from integrated semiconductor quantum dot emitter- all dielectric multifunctional light manipulating unit arrays
Abstract
This proposal seeks funds under the DURIP FY2018 (PA-AFRL-AFOSR-2017-0001) forthe augmentation of equipment needed to fully implement the research proposed in our AFOSRapproved proposal “Addressable surface-curvature driven mesa top single quantum dot basedsingle photon source array integrated on-chip with dielectric light manipulating elements“(Internal Proposal Number 17RT0223).The research proposed builds upon the groundbreaking success of our AFOSR supported (grant no. FA9550-10-01-0066) work that synthesized spatially-ordered arrays of single quantum dots (SQDs) based single photon emitters that are at the core of realizing the long standing goal of on-chip integrated quantum optical circuits that underpin quantum information processing nanophotonic systems. Moving towards this goal demands each SQD emitter be surrounded by optical elements that provide the required functions of enhancement of the SQD emission rate (Purcell effect), lossless directing and guiding the emitted photons, and beam splitting. Our purely growth-controlled novel approach to synthesizing the SQD arrays inherently lends itself, through the overgrowth of a morphology planarizing overlayer, to creating the platform for the subsequent use of the well- developed 2D photonic crystal approach to fabricating the above noted functional elements, or an alternative ground-breaking approach introduced by us that provides these multiple functions through codesigned interacting assemblies (light manipulating units) of sub-wavelength size dielectric building blocks (DBBs) spatially organized around each light emitting single quantum dot in the array. To enable full characterization of these unique nanophotonic systems, the requested equipment comprises (1) a high resolution high throughput spectrometer ; (2) low dark count, low jitter, and high efficiency superconducting nanowire detector system; and (3) upgraded source cell and control system for the quantum dot growth system.
