A new publication from Opto-Electronic Science; DOI 10.29026/oes.2024.230052 discusses structured light beams with controllable polarization along arbitrary trajectories. A structured light refers to ...

It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave ...

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 ...

Release Summary Text: In atomically thin semiconductors, enhancing the frequency-doubled light signal has come at the cost of losing polarization information tied to the valley degree of freedom.

Scientists report a new method that achieves for the first time valley polarization in centrosymmetric bulk materials in a non-material-specific way. This 'universal technique' may have major ...
