Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new ...

Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That's ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Researchers have produced a record-thin optical quarter-waveplate from the two-dimensional material niobium oxychloride (NbOCl2), measuring roughly 269 nanometers thick and operating at a wavelength ...

Scientists explore the physics of how polarization-filtered colors emerge, how they can be controlled, and why subtle changes in viewing angle, sample orientation, and the order of layers of films ...
