New Publication: Bottom-up, chip-scale engineering of low threshold, multi- quantum well microring lasers

Computation with light instead of electricity will increase speed and energy efficiency. We show a route to growing lasers directly onto chips with high repeatability to enable this technology.

Invited talk at IUMRS ICAM-ICMAT 2023, Singapore

Group PI Patrick was invited to give a talk at the International Union of Materials Research Society meeting in Singapore. The talk, entitled 'Semiconductor Optimization Using Functional Inhomogeneity: High-Throughput Characterization for Semiconductor Nano-Lasers' reviewed recent work from the group to optimize nanolasers. The meeting also provided an opportunity to meet

New Publication: Holistic Nanowire Laser Characterization as a Route to Optimal Design

Group postdoc Stephen Church has just had a paper accepted into Advanced Optical Materials. In this work, he reports the study of thousands of individual nanowire lasers, using advanced statistical methods to identify a route to optimization. Photonic integrated circuitry is rapidly emerging as an alternative to electronics for specialist

New Paper: Optical Characterisation of Nanowire Lasers

Group postdoc Stephen Church and PhD student Ruqaiya Al-Abri collaborated with Dhruv Saxena at Imperial College London to produce a review of methods to characterise nanowire lasers. This article, forming part of a celebration issue for the birthday of colleague Prof. Chennupati Jagadish (at the Australian National University) seeks to

Physics and applications of semiconductor nanowire lasers - book chapter published

Patrick has contributed a chapter to the new textbook “Semiconductor Nanodevices“, edited by Prof. David Ritchie (University of Cambridge) and published by Elsevier. In his chapter on Physics and Applications of Semiconductor Nanowire Lasers, common features, design rules, seminal works and an outlook for future development are provided.

MRS Spring - virtual conference presentation

Patrick gave a virtual presentation on “High-Throughput Correlative Microscopy and Spectroscopy for Nano-Laser Development” in the CT05 “AI and Automation for Materials Design” session.

Seminar : LIV.DAT

Patrick gave a virtual seminar at Liverpool Big Data Science Centre for Doctoral Training (LIV.DAT) on “Big-data for nano-electronics“. Thanks to Prof. Carsten Welsch for the invitation!

New Paper: Heterostructure and Q-factor engineering for low-threshold and persistent nanowire lasing

Group PhD student Stefan Skalsky’s paper on semiconductor nanowire lasing has just been published in Light: Science and Applications. In this new work, Stefan used his newly developed Interferometric Time-Correlated Single Photon Counting system (i-TCSPC) to measure the coherence length of laser emission from nanowires grown by the Liu

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 - Threshold reduction and yield improvement of semiconductor nanowire lasers via processing-related end-facet optimization

Arturo has had a paper accepted for publication in Nanoscale Advances, describing the impact of the transfer process on the morphology and threshold of semiconductor nanowire lasers. While many studies have sought to improve the threshold for lasing in semiconductor nanowire lasers, the role of process has not been significantly
