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 ...

Although its name and likeness are ubiquitous, very little is actually known about the nautilus, a sea creature distinguished by its hallmark spiral-shaped shell. However, three new species of ...

The optical rotatum's logarithmic spiral follows a pattern found often in nature, including nautilus shells. Credit: Capasso Lab / Harvard SEAS The optical rotatum's logarithmic spiral follows a ...

Pushing the limits of structured light, applied 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 ...
