Polygonal optical vortices—a new subset of optical vortices—uniquely enable numerous applications due to the new degrees of freedom offered and their customizable light intensity structure. So far, ...

Imagine a whirlpool spinning in a river, or a tornado swirling through the sky. They don't just spin on the spot: they travel forward while maintaining that spiraling motion inside them. These ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two ...

This Collection supports and amplifies research related to SDG 9 - Industry, Innovation and Infrastructure. The ability to control the phase, polarization, and intensity of light is extensively ...

A new Doctoral Network coordinated by Tampere University has secured €4.4 million in funding from the European Union’s Marie Skłodowska-Curie Actions (MSCA) programme. The High-Power Optical Vortices ...

Optical vortex beams, characterized by their helical phase fronts and orbital angular momentum (OAM), are pivotal in applications such as high-capacity communication, optical manipulation, and quantum ...

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 ...
