Personal profile

Personal Statement

Paulo Hisao Moriya got his B.Sc. (2009), M.Sc. (2012) and Ph.D. (2016) in Physics from University of São Paulo (Brazil). Since 2016, he is a Postdoctoral Research Associate at the Institute of Photonics, University of Strathclyde (Glasgow, UK), investigating and developing compact laser systems at novel wavelengths with high stabilility based in VECSEL (Vertical-External-Cavity Surface-Emitting-Laser) technology for the UK National Quantum Technology Hub for Sensors and Metrology/in Sensors and Timing. His main contributions are related to lasers targeting both laser cooling transitions of neutral Strontium for Optical Clocks. It includes a 1-W, intracavity frequency-doubled InGaAs VECSEL at 461 nm and AlGaInP VECSEL at 689 nm with output power > 150 mW and a record narrow linewidth for this technology of 125 Hz.

In his academic career, he theoretically studied the effect of interatomic interactions in the superradiance phenomena for his masters but his main contributions are related to his PhD work in experimental cold atoms to investigate collective and cooperative effects in light scattering from cold Strontium clouds. His PhD work required also work to improve an existing experimental apparatus and development of new laser systems for his research. As a result, his skill set is related to: electronics (including RF); high and ultra-high vacuum; spectroscopy; optics; light analysis; lasers systems; feedback systems for laser frequency, temperature and current stabilisation. He was also Post-Doctoral Fellow in the University between April and October 2016 to continue the research work and move towards the generation of Bose-Einstein condensates of Strontium.

His research interests are the development of portable, compact, single frequency and narrow linewidth operation of lasers. It also includes laser frequency stabilisation, noise reduction techniques, the development of stable reference cavities, electronics and instrumentation.
