The Photonics Group at the University of Bristol

The Photonics Group at Bristol University is lead by Prof. John Rarity, and comprises both the Centre for Quantum Photonics and Classical Photonics, spanning the Dept of Electrical and Electronic Engineering, and the School of Physics.


SPANGL4Q Co-ordinator

Co-ordinator, Dr. Ruth Oulton

Co-ordinator Dr. Ruth Oulton is an EPSRC Career Acceleration Fellow at the University of Bristol, with a joint appointment in the School of Physics and the Dept. of Electrical and Electronic Engineering.


Ruth works on quantum dot photonic structures for quantum information processing applications.  Her past work spanned spin dynamics of electrons and nuclei at TU Dortmund, and quantum dot photonic structures at the University of Sheffield.


Ruth also has other research interests in photonic light-matter interactions in living organisms.

Dr Hamish McAlpine is the project manager for SPANGL4Q, assisting with reporting and dissemination of SPANGL4Q's activities.
