325:), high power short pulse laser delivery through fibre, and applications in quantum and atomic physics. Belardi and Knight proposed the hollow-core "nested-ring" design for photonic fibres, at the beginning of 2014. 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.

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. This work
