The Optical Society presented the award in recognition of ‘contributions to optics and especially to optical momentum, including the optical spanner, the use of orbital angular momentum in communication systems, and an angular form of the Einstein-Podolsky-Rosen paradox.’

The laws of reflection are well known, established by Fresnel more than 200 years ago. Neal Radwell and collaborators show in their Nature Communications article that simple back-reflection from solid glass cones still holds surprises today.

As just published in Nature Communications, Peter Morris, Reuben Aspden and colleague in the Optics Group in collaboration with Scientist Canada have created an image of a wasp wing using just 50,000 particles of photons, none of which ever directly interacted with the wing itself.

Writing in Nature Communications, Martin Lavery, within a collaboration led by the University of Southern California had extended the use of orbital angular momentum to mm-wave beams as part of a communication system.

By applying a back-scattered light source, Martin Lavery and colleagues have observed white light with a different kind of Doppler shift, one that arises from the rotation of an object rather than its motion toward or away from an observer.

Writing in Science Magazine, Martin Lavery and Miles Padgett of the Optics Group with collaborators Stephen Barnet and Fiona Speirits from Strathclyde has shown that the familiar change in pitch of an approaching ambulance siren can also apply to spinning objects even when their linear velocity is zero.

Dr Johannes Courtial from the School of Physics & Astronomy recently appeared as an expert in an episode of the BBC programme "Coast". He explained the physics of the "green flash", an atmospheric phenomenon that can cause the top of sun to appear green as it is setting or rising above the sea.

Professor Miles Padgett has been elected to fellowship of the Optical Society of America (OSA) in recognition of his "experimental and theoretical advances in the interplay of orbital and spin angular momentum of light and its interaction with matter".

The speed of light is a constant only in space. When light travels through glass, movement of the glass drags the light with it too. Spinning a window as fast as you can is predicted to rotate slightly the image of the world behind it.
