Jonathan C. Knight

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).

Knight is interested in the behaviour of light in microstructured materials, and in the physics of optical fibres.{{Google scholar id | YDjo1I8AAAAJ | Jonathan Knight}} Working with Russell and Tim Birks, he designed, fabricated and demonstrated a number of novel forms of optical fibre waveguide with previously unobtainable characteristics.{{cite web|title=Physics professors receive Rank Prize for optical fibre discoveries|url=https://www.myscience.org.uk/wire/physics_professors_receive_rank_prize_for_optical_fibre_discoveries-2018-Bath/|website=15 February 2018|date=15 February 2018 |publisher=My Science}}{{cite web|first1=Gache|last1=Gabriel|title=Newly Designed Optical Fiber Is Hollow|url=https://news.softpedia.com/news/Newly-Designed-Optical-Fiber-is-Hallow-76654.shtml/|website=18 January 2008|date=18 January 2008 |publisher=Softpedia}} This work has led to a range of outcomes including the commercialisation{{cite web|last1=Sabert|first1=Hendrik|last2=Knight|first2=Jonathan|title=Hollow-Core Fibers Seek the 'Holey' Grail|url=https://www.photonics.com/Articles/Hollow-Core_Fibers_Seek_the_Holey_Grail/a16628/|website=August 2003|publisher=Photonics Spectra}}^,{{cite news|last1=Lloyd|first1=Hywel|title=8m deal as city firm sells assets to rival|website=10 August 2004|publisher=Bath Chronicle}} of a new form of light source (supercontinuum), high power short pulse laser delivery through fibre, and applications in quantum and atomic physics.{{cite web|last1=Wadsworth|first1=William |last2=Knight|first2=Jonathan|last3=Birks|first3=Tim|title=State-of-the-Art Photonic Crystal Fiber|url=https://www.osa-opn.org/home/articles/volume_23/issue_3/features/of-the-art_photonic_crystal_fiber/|website=1 March 2012|publisher=Optics and Photonics News}} Belardi and Knight proposed the hollow-core "nested-ring" design for photonic fibres, at the beginning of 2014.{{cite web|last1=Wallace|first1=John|title=Hollow-core antiresonant optical fibers: Part II|url=https://www.laserfocusworld.com/articles/2014/10/hollow-core-antiresonant-optical-fibers-part-ii.html/|website=05 March 2019|date=28 October 2014 |publisher=Laser Focus World}} 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.{{cite web|title=New laser achieves wavelength long sought by laser developers|url=https://phys.org/news/2016-02-laser-wavelength-sought.html/|website=05 March 2019|publisher=Phys.Org}}
