Photonics West 2020 - presentation and proceedings

The talk and proceedings for Patrick’s recent invited talk at Photonics West is now available online. “A needle in a needlestack” describes how our recent work on Manchester on inhomogeneity can provide more information about functional performance than a homogeneous population can. Reference: A needle in a needlestack: exploiting

New arXiv paper: Defect-Free Axial GaAs/GaAsP Nanowire Quantum Dots with Strong Carrier Confinement

We have uploaded a new paper on quantum-dot-in-nanowire structures to the arXiv. Working with colleagues at University College London, the University of Warwick, the University of Sheffield and the University of Copenhagen, this work demonstrates the growth of high-quality GaAs quantum dot inclusions in a GaAsP nanowire, with evidence for

Invited Talk at Photonics West 2020

Patrick gave an invited talk at Photonics West 2020 in San Francisco, in the session Novel Nano Structure. This talk convered recent work on ultra-low threshold nanowire lasers and experimental end-cavity reflectivity measurements in nanoscale systems.

New Paper: Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems

Our collaborative work on the selection, transfer and testing of semiconductor nanowire lasers has now been published in Nano Letters. In this work, growth colleagues at ANU prepared nanowire lasers which were characterised at Manchester. This characterisation was used to select bins of nanowires, which were transferred using a cutting

Seminar at the University of Sheffield

Patrick gave a seminar at the University of Sheffield, where he was kindly hosted by Dr Jenny Clark of the Department of Physics and the Sheffield Laser Lab. He spoke about exploiting functional inhomogeneity for optimizing nano-optoelectronics, and learnt a lot about ultrafast spectroscopy for singlet fission.

New arXiv paper - Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems

Our new paper produce in collaboration with Michael Strain and Antonio Hurtado (University of Strathclyde) and the Jagadish group (Australian National University) is now available on the arXiv. In this work, we combine high-quality nanolaser growth (ANU) with high-throughput optical spectroscopy (Manchester) and high-speed pick-and-place technology (Strathclyde) to demonstrate scaled-up

Photonics Online Meetup

The OMS group will host the University of Manchester hub for the Photonics Online Meetup. This is the first free, online-only photonics conference, to be held from 7pm-midnight on Monday 13th January 2020. Any staff or students who wish to attend should contact Patrick Parkinson.

Conference Talk: Arturo at MRS Fall

Group PhD student Arturo has given a talk at MRS Fall 2019 in Boston. He spoke on “Nanolaser Optimization through Statistical Optoelectronic Analysis“.

Viva in Manchester

Patrick was the internal examiner for (Jack) Chun-Ren Ke, a student in the group of Prof. Wendy Flavell who has worked on surface science of hybrid-perovskite optoelectronic materials. The external examiner was Prof. Sven Schroeder of the University of Leeds.

Viva in Manchester

Patrick was the internal PhD examiner for Henry Maguire in the Nazir group at the University of Manchester. Henry submitted his thesis on “Optically driven nanostructures with strong vibronic coupling“, and Dr Alex Chin was the external examiner.
