Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to ...

Researchers embedded a liquid crystal layer into a waveguide that was created with direct laser writing (pictured). The resulting hybrid device can be used to change the polarization of light ...

image: a, Schematic of the proposed all-in-one polarizer that can function at an arbitrary position on the Poincaré sphere by design based on a dielectric metasurface composed of dimerized nanopillars ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

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 ...
