Design of photonic microcavities in hexagonal boron nitride
Beilstein Journal of Nanotechnology, 2018 We propose and design photonic crystal cavities (PCCs) in hexagonal boron nitride (hBN) for diverse photonic and quantum applications. Two dimensional (2D) hBN flakes contain quantum emitters which are ultra-bright and photostable at room temperature. To

Quasichiral Interactions between Quantum Emitters at the Nanoscale [PDF]
Physical Review Letters, 2019 We present a combined classical and quantum electrodynamics description of the coupling between two circularly-polarized quantum emitters held above a metal surface supporting surface plasmons. Depending on their position and their natural frequency, the emitter-emitter interactions evolve from being reciprocal to nonreciprocal, which makes the system ...

Large-scale quantum-emitter arrays in atomically thin semiconductors
Nature Communications, 2017 Quantum emitters have been recently isolated in 2D materials, yet their spatial controllability remains an open challenge. Here, the authors devise a method to create arrays of quantum emitters in WSe2 and WS2, by taking advantage of the strain ...

Quantum Resonator as a Directional Quantum Emitter
Advanced Quantum TechnologiesABSTRACT Single‐photon sources are essential for testing fundamental physics and for the development of quantum technologies. In this work, a single‐photon source is investigated, based on a two‐photon Jaynes–Cummings system, where the resonator works as the quantum emitter rather than the two‐level system. This role reversal provides

On-Chip Quantum Photonics Using Integrated Quantum Dot Emitters [PDF]
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018 On-chip quantum photonics relies on the integration of efficient single-photon sources with advanced quantum- optical circuits. In this presentation, I will review progress at the University of Sheffield on a chip-compatible III-V semiconductor platform in which InGaAs quantum-dot (QD) single-photon emitters are integrated into GaAs photonic circuits ...

Quantum Emitters in Rhombohedral Boron Nitride
Advanced Optical MaterialsAbstractRhombohedral boron nitride (rBN) is an emerging wide‐bandgap van der Waals (vdW) material that combines strong second‐order nonlinear optical properties with the structural flexibility of layered 2D systems. It is shown that rBN hosts optically‐addressable spin defects and single‐photon emitters (SPEs).

Resonantly enhanced thermal emitters based on nanophotonic structures
, 2015 The manipulation of photons, especially the control of spontaneous emission, has become a core area of photonics research in the 21st century. One of the key challenges is the control of the broadband emission profile of thermal emitters.

Charge and energy transfer of quantum emitters in 2D heterostructures
, 2020 Graphene is often used as an acceptor in highly efficient energy transfer processes between its electrons and neighbouring optical emitters such as quantum dots, fluorescent molecules and color centres in crystals.
