Dr Paul Gow PhD

Personal homepage
https://paulcgow.wordpress.com

Paul obtained his PhD working in the Quantum Light and Matter (QLM) group at the University of Southampton in 2016. His PhD thesis focused on developing novel emitters for Terahertz (light between microwaves and infra-red) to be used for spectroscopy and integration with other devices.

After completing his PhD, Paul joined the Optical Engineering & Quantum Photonics group. His research involves fabricating on-chip photonic devices which use light instead of electricity for sensing, optical integration, and quantum technology. Paul is investigating the use of UV and Infra-red lasers for machining and processing of silica (glass) and other materials. He is also involved with ultra-precision machining of glass and silicon, using dicing and milling techniques to achieve optical grade finished without the need for polishing.

In his spare time Paul enjoys playing guitar, mountain biking, and performing close up magic.

Research

Research interests

Paul is currently developing a new Direct UV Writing system based on a 213 nm wavelength laser for fabricating planar silica integrated optics. These devices will be used to shrink entire lab benches of mirrors optics down to a fibre-coupled, chip-scale device capable of coupling light in to and out of atom traps.

He has been involved with the EPSRC funded NQIT (Networked Quantum Information Technologies) quantum hub project to develop and test a fibre-optic network for quantum entanglement of Strontium ion traps in collaboration with the University of Oxford.

Key words: Photonic devices, Optical waveguides, Bragg gratings, Direct laser writing, Laser materials processing, Optoelectronic devices, Quantum technology, Ultra precision machining, Optical sensors.
