Addressable Surface-Curvature Driven Mesa Top Single Quantum Dot Based Single Photon Source Array Integrated On-Chip with Dielectric Light Manipulating Elements

This Final Technical Report briefly captures the highlights of the accomplishments under grant number FA9550-17-1-0353 (Program Manager Dr. Gernot Pomrenke) whose basic goal was to explore the potential of our new class of spatially ordered arrays of single quantum dots (SQD) dubbed mesa-top single quantum dot (MTSQD) as on-demand single photon sources (SPS). Spatially-ordered arrays of quantum emitters are the essential, but hitherto missing, component for the long-sought platform for fabricating on-chip integrated quantum optical circuits. During this period (Sept.15, 2017 Dec. 31, 2022), despite the unanticipated delays and disruptions due the COVID-19 induced shutdowns from March 2020 to July 2021, we successfully reached several major milestones critical to realizing quantum optical circuits. The driving vision, goals set for this grant, and accomplishments are captured in this final technical report, as are some comments on the continuing efforts. The advances made under this grant have brought the field one essential step closer to realizing on-chip scalable quantum photonic systems.
