Control of fluorescence in quantum emitter and metallic nanoshell hybrids for medical applications

, 2017
We study the light emission from quantum emitter and double metallic nanoshell hybrid systems. Quantum emitters act as local sources which transmit their light efficiently due to a double nanoshell near field.

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 ...

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 ...

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Cascaded two-photon nonlinearity in a one-dimensional waveguide with multiple two-level emitters

, 2013
We propose and theoretically investigate a model to realize cascaded optical nonlinearity with few atoms and photons in one-dimension (1D). The optical nonlinearity in our system is mediated by resonant interactions of photons with two-level emitters ...

Delocalized single-photon Dicke states and the Leggett- Garg inequality in solid state systems

, 2012
We show how to realize a single-photon Dicke state in a large one-dimensional array of two- level systems, and discuss how to test its quantum properties.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Enhanced collective Purcell effect of coupled quantum emitter systems

, 2019
Cavity-embedded quantum emitters show strong modifications of free space radiation properties such as an enhanced decay known as the Purcell effect. The central parameter is the cooperativity $C$, the ratio of the square of the coherent cavity coupling ...
