Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical ...

A project at Finland's Tampere University has secured €4.4 million in funding to further its research into optical vortices. The High-Power Optical Vortices (HiPOVor) project will train 15 doctoral ...

By transmitting selective optical vortex modes exclusively unidirectionally, the developed device largely reduces detrimental backscattering to a minimum. The scientists emphasize the great practical ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has been ...

(Nanowerk News) An optical vortex is identified as a phase singularity encircled with helical wavefront, and thanks to its unique properties including its carried orbital angular momentum (OAM) ...

Can light behave like a whirlwind? It turns out it can—and such "optical tornadoes" have now been created in an extremely ...
