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…
Tunable multi-photon correlations from a coherently driven quantum dot
Thomas K. Bracht, Rachel N. Clark, Petros Androvitsaneas +7
Mixing the fields generated by different light sources has emerged as a powerful approach for engineering non-Gaussian quantum states. Understanding and controlling the resulting p…
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…
Tunable frequency conversion in doped photonic crystal fiber pumped near degeneracy
Leah R Murphy, Mateusz J Olszewski, Petros Androvitsaneas +5
Future quantum networks will rely on the ability to coherently transfer optically encoded quantum information between different wavelength bands. Bragg-scattering four-wave mixing…

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…
Direct-write projection lithography of quantum dot micropillar single photon sources

We have developed a process to mass-produce quantum dot micropillar cavities using direct-write lithography. This technique allows us to achieve high volume patterning of high aspe…
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…
Stabilisation of an optical transition energy via nuclear Zeno dynamics in quantum dot-cavity systems
