A photon enters an extraordinarily intense laser field. When it exits, its polarization has rotated, as though empty space ...

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing ...

Emerging applications now require 5- and 6-degree-of-freedom alignment systems capable of handling larger payloads and more ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication.

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 ...

Researchers have produced a record-thin optical quarter-waveplate from the two-dimensional material niobium oxychloride ...

(Nanowerk News) 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 ...
