Personal statement

Paulo Hisao Moriya is a Research Associate at the Institute of Photonics researching and developing high performance, narrow linewidth lasers based in VECSEL technology for the UK National Quantum Technologies Hub in Sensor and Timing (Sensors and Metrology for Phase I). He got his B.Sc. (2009), M.Sc. (2012) and Ph.D. degrees (2016) in Physics from University of São Paulo (Brazil), with emphasis in Theoretical Quantum Optics (M.Sc.) and Experimental Cold Atoms and Atomic Physics (Ph.D.). He also worked at University of São Paulo as post-doctoral fellow (Apr-Oct 2016). His research interests are mainly focused in the development of portable, compact, single frequency and narrow linewidth operation of optically pumped VECSELs for cold atoms-based quantum technologies. It also includes frequency stabilisation/noise reduction techniques, stable reference cavities and instrumentation.
