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, ...

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 ...

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for ...

Single-packet spatiotemporal optical vortices (STOVs) with transverse orbital angular momentum (OAM) have recently garnered significant attentions. Nevertheless, more advanced applications require ...

A team has been developing a new type of laser-induced forward transfer (LIFT) for laser printing using an optical vortex, which has been dubbed OV-LIFT. The team succeeded in printing crystals with ...

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 ...

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...

Pushing the limits of structured light, physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create unique ...

A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by “nulling” out the light of the parent star by ...

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 ...
