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 unique patterns. The way the light behaves resembles spiral shapes common in nature.

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ... Photonics researchers have introduced a novel method to control a light beam with another beam through a unique plasmonic metasurface in a linear medium at ultra-low power. This simple linear ...
Researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings could have huge implications for optical communication ... Propagate light through any kind of medium -- be it free space or biological tissue -- and light will scatter. Robustness to scattering is a common requirement for communications and for imaging ...Tiny, Soft Robot Flexes Its Potential as a Life Saver
