Summary

 

Summary

Dr. William Kerridge-Johns holds an Imperial College Research Fellowship based in the Photonics Group. His research is focussed on developing novel lasers to generate high-power optical vortex beams.

Optical vortex beams have a corkscrew structure giving them orbital angular momentum. This type of spatially structured light enables a wide variety of applications by providing another degree of control to laser output. William’s research is based on the interface between structured light generation and laser design, which creates new technologies and capabilities for optical vortex research at high power. He is interested and involved in tailoring these devices towards a diverse range of applications.

Currently open to PhD applications based in this dynamic research area, please contact for more information.
