One important form is called an optical vortex beam. Unlike an ordinary light beam with a flat wavefront, an optical vortex beam has a twisted, corkscrew-like phase structure and a dark center, much ...
In recent years, optical vortices have attracted extensive attention in laser advanced manufacturing because of their annual intensity distribution and orbital angular momentum. Compared with the ...
The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the ...

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 ...
To study nanoscale patterns in tiny electronic or photonic components, a new method based on lensless imaging allows for near-perfect high-resolution microscopy. This is especially important at ...
