HYBRID, ROOM-TEMPERATURE, QUANTUM ON CHIP PHOTONIC SYSTEMS: INTEGRATING QUANTUM EMITTERS WITH NANOPLASMONICS
Abstract
Recent years have seen tremendous progress in nanophotonics spanning fundamentally new optical effects and novel technologies such as metasurfaces, near-zero-index optics, and topological photonics, to name a few. The emerging area of quantum photonics is just beginning to leverage the most recent advancements in nanophotonics and plasmonics to address the critical need in developing efficient, compact on-chip quantum devices for future applications in quantum communication systems, sensing, and quantum photonic computing. This proposal will build on current developments in the areas of metasurfaces and nanoplasmonics and explore both fundamental science aspects and practical applications of hybrid quantum photonic systems. We will merge the concepts of plasmonic nanoantennas and metasurfaces with two-dimensional (2D) and quantum materials, with the focus on materials exhibiting quantum emission. Our goal is to employ plasmonic nanoresonators and couple them with the emerging 2D/quantum materials such as hexagonal Boron Nitride (hBN), transition metal dichalcogenides (TMDCs) and perovskitequantum wells to both unlock new phenomena and develop on-chip, quantum photonic devices, specifically, room-temperature indistinguishable single-photon sources and quantum sensors. Building upon the team’s recent demonstration that plasmonic nanocavities dramatically enhance emission in single nitrogen-vacancy centers in nanodiamonds, we will explore hybrid 2D quantum materials coupled with plasmonic structures/metasurfaces that could bring new fundamental insights into advanced engineering of quantum radiation as well as on-chip quantum devices. The proposed topic has a strong fundamental component on discovering new quantum emitters based on defects and engineering their properties in novel, hybrid material platforms. The proposed approach leverages team’s significant advancements in nanoplasmonics and is envisioned to bring unique advantages to quantum optics and on-chip devices.Approach. Solid-state defects acting as quantum emitters are at the core of modern quantum photonic technologies. However, due to weak interaction between light and matter, efficient incorporation of quantum defects into on-chip platforms remains an outstanding challenge. It has recently been shown that single photon sources with the appropriate optical properties can be created by coupling naturally existing emitters in solids to nanoscale plasmonic cavities. In this project, we will explore novel approaches for creating single photon emitters in 2D materials such as hBN, TMDCs and perovskite quantum wells and for coupling those emitters to nanoplasmonic structures to enhance light-matter coupling. The main goals of this effort are 1) to investigate novel methods to deterministically create single photon emitters with the required and tailorable optical properties in the above-mentioned quantum materials; 2) to achieve controllable incorporation/integration of plasmonic cavities with emitters in 2D materials. The proposed research novelty is two-fold and includes innovative studies of both constituent 2D and quantum wellmaterials properties, including growth and optimization, as well as design, fabrication and characterization of plasmonic metasurface-assisted quantum emitters. In accord with the goals, the research objectives of the project are to i) develop the fabrication of emitters with nm-scale precision in thin flakes of 2D systems and other quantum materials and to ii) integrate quantum emitters with plasmonic and dielectric structures. We will develop theoretical models, perform numerical simulations and optimize experimental realization of plasmonic nanocavities/metasurfaces integrated with quantum emitters; obtain the most efficient plasmonic structures and integration routes as well as gain insights into emitter-cavity optical properties.
