One way to quantum technology. My group has published paper today on quantum light emission from colour centres in Gallium Nitride at https://doi.org/10.1063/5.0085257. This semiconductor is used in numerous everyday applications including room lighting, car headlamps, high power electronics and blu-ray (if you are old enough to remember what that is?). We showed the use of a half-sphere lens on the semiconductor can greatly enhance the magnification with which we image these colour centres, and also increases the intensity of the emission. Well done to all the team on getting this paper out. The scanning electron microscope in the Cardiff Cleanroom. A visit to our new labs! Goodbye San Francisco. It's is a pleasure to be in San Francisco at Photonics West this week, giving an invited talk on our research, and representing the UK's Hub in Quantum Computing and Simulation. Part of my talk is about SPEs (Single Photon Emitters) so I was amused to be greeted by this in the entrance. #photonics #photonicswest #quantum New paper on quantum technologies in diamond enabled by laser processing published in Appl. Phys. Lett. 120, 020502 (2022); https://doi.org/10.1063/5.0080348 from the #LasIonDef project. Group Xmas Lunch 2021! PhD student Rachel, in front of a poster of herself at the Impact Conference in Cardiff today. Congratulations to Rachel on being voted 'best talk of the day'.
