Jonathan C. Knight, (born 1964, in Lusaka) is a British physicist. He is the Pro Vice-Chancellor (Research) for the University of Bath[1] where he has been Professor in the Department of Physics since 2000, and served as head of department.[2] From 2005 to 2008, he was founding Director of the university's Centre for Photonics and Photonic Materials.

Education

Knight studied at the University of Cape Town where he obtained his B.Sc. (Hons), M.Sc. and PhD. His doctoral thesis was on whispering gallery mode microlasers. He did postdoctoral research at the École Normale Supérieure (Paris, 1994–1995) and at the Optoelectronics Research Centre (University of Southampton, 1995–1996).

Research

Knight is interested in the behaviour of light in microstructured materials, and in the physics of optical fibres. Working with Russell and Tim Birks, he designed, fabricated and demonstrated a number of novel forms of optical fibre waveguide with previously unobtainable characteristics.[3] [4] This work has led to a range of outcomes including the commercialisation[5] ,[6] of a new form of light source (supercontinuum), high power short pulse laser delivery through fibre, and applications in quantum and atomic physics.[7] Belardi and Knight proposed the hollow-core "nested-ring" design for photonic fibres, at the beginning of 2014.[8] Together with William Wadsworth, Knight co-created a new kind of laser capable of pulsed and continuous mid-infrared (IR) emission between 3.1 and 3.2 microns, a spectral range that has long presented a major challenge for laser developers.[9]
