Axicons are devices that allow light to be focused along a volume, in contrast to normal lenses that focus light on a single point. Thanks to the use of liquid crystal, CEMDATIC researchers can reconfigure the developed axicons by means of electronic signals. The ability to reconfigure these devices may have applications in laser processing or optical traps. Furthermore, these axicons allow the modification of a property of light known as topological charge, enabling higher capacity optical communications by using light quantum properties.
CEMDATIC researchers have just published their latest work on reconfigurable axicons in the prestigious journal Scientific Reports:
