Biography

Olivier Krebs obtained his doctorate in 1998 at Université Paris VI. The topic was birefringence for certain semiconductor quantum wells. He was first recruited to the CNRS Pierre Aigrain Laboratory (ENS-Paris), to study the engineering possibilities of birefringence and  the Pockels effect in quantum well superlattices. In 2002, he joined the Photonics and Nanostructures Laboratory (now the Centre for Nanoscience and Nanotechnology since 2016). There, he developed new activities on spin properties in semiconductor quantum boxes. He became a research director in 2012 and continued to work on this branch of fundamental physics. He also contributed to research that aims to use quantum boxes as a source of single photons and as potential quantum memory, in the context of quantum technologies.

  • Research topics​ Single spin properties and manipulation in semiconductor quantum boxes
