Democratising Optical Orbital Angular Momentum: a Set of Cost-Effective Tools
Natasha Bierrum, Lyuxuan Chen, Ananya Kudaloor +9
Classical and quantum optical communication has gained popularity and momentum in recent years, with growing investment and innovation in quantum technologies. However, the main te…
Aspheric lens design proposal for near-perfect mode-matching of a broadband quantum dot micropillar to a single-mode fibre
Yichen Zhang, David Dlaka, James McDougall +5
Quantum dots in micropillars are one of the most promising options for a bright, deterministic single photon source. While highly efficient devices (>95%) have been designed, there…
Room temperature spin injection into commercial VCSELs at non-resonant wavelengths
Timur Almabetov, Petros Androvitsaneas, Zhongze Ren +3
Spin lasers leverage electron spin-polarisation to control photon polarisation, offering the potential for lower thresholds, rapid modulation, and all-optical data processing. We r…
Nanoring Tamm Cavity in the Telecommunications O band
Huili Hou, David Dlaka, Jon Pugh +2
Quantum and classical telecommunications require efficient sources of light. Semiconductorsources, owing to the high refractive index of the medium, often exploit photonic cavities…
Design principles for >90% efficiency and >99% indistinguishability broadband quantum dot cavities
David Dlaka, Petros Androvitsaneas, Andrew Young +3
Quantum dots have the potential to be the brightest deterministic single photon source with plausible high end applications in quantum computing and cluster state generation. In th…
Coherent scattering from coupled two level systems
Thomas Nutz, Samuel T. Mister, Petros Androvitsaneas +5
We study the resonance fluorescence properties of an optically active spin 1/2 system, elucidating the effects of a magnetic field on the coherence of the scattered light. We deriv…
Reflection by two level system: phase singularities on the Poincaré hypersphere
Ben Lang, Edmund Harbord, Ruth Oulton
We consider the reflection of a photon by a two-level system in a quasi-one-dimensional waveguide. This is important in part because it forms the backdrop for more complicated prop…
Quantum modulation of a coherent state wavepacket with a single electron spin
P. Androvitsaneas, A. B. Young, T. Nutz +9
The interaction of quantum objects lies at the heart of fundamental quantum physics and is key to a wide range of quantum information technologies. Photon-quantum-emitter interacti…
High extraction efficiency source of photon pairs based on a quantum dot embedded in a broadband micropillar cavity
Laia Ginés, Magdalena Moczała-Dusanowska, David Dlaka +9
The generation of photon pairs in single quantum dots is based on a process that is, in its nature, deterministic. However, an efficient extraction of these photon pairs from a hig…
Perfect Chirality with imperfect polarisation
Ben Lang, Dara P. S. McCutcheon, Edmund Harbord +2
Unidirectional (chiral) emission of light from a circular dipole emitter into a waveguide is only possible at points of perfect circular polarisation (C points), with elliptical po…
A Tamm Plasmon-Porous GaN Distributed Bragg Reflector Cavity
Jon R. Pugh, Edmund Harbord, Andrei Sarua +4
This paper reports on design, measurement and optimisation of a Tamm plasmon metal-DBR cavity for use in the green part of the visible spectrum. It uses an optimised silver layer t…
Telecommunication wavelength confined Tamm plasmon structures containing InAs/GaAs quantum dot emitters at room temperature
Matthew Parker, Edmund Harbord, Lifeng Chen +4
We experimentally demonstrate gold microdisc structures that produce confined Tamm plasmons (CTPs), interface modes between a metal layer and a distributed Bragg reflector, resonan…
A model for confined Tamm plasmon devices
Mike Adams, Ben Cemlyn, Ian Henning +3
It is shown that cavities formed between a multilayer quarter-wave Bragg reflector and a metal mirror which support Tamm plasmons can be modelled by using a hard-mirror approximati…
Efficient deterministic giant photon phase shift from a single charged quantum dot
P. Androvitsaneas, A. B. Young, J. M. Lennon +8
Solid-state quantum emitters have long been recognised as the ideal platform to realize integrated quantum photonic technologies. We use a self-assembled negatively charged QD in a…
P-shell carriers assisted dynamic nuclear spin polarization in single quantum dots at zero external magnetic field
C. F. Fong, Y. Ota, E. Harbord +2
Repeated injection of spin polarized carriers in a quantum dot leads to the polarization of nuclear spins, a process known as dynamic nuclear spin polarization (DNP). Here, we repo…
A charged quantum dot micropillar system for deterministic light matter interactions
Petros Androvitsaneas, Andrew B. Young, Chritian Schneider +8
Quantum dots (QDs) are semiconductor nanostructures in which a three dimensional potential trap produces an electronic quantum confinement, thus mimicking the behaviour of single a…
