Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have ...

A laser beam hits a meta-grating that directs the light waves even at steep incidence angles, thus enabling new optical ...

This grating can therefore be used either to steer ... The robustness of acousto-optical tuning means that it suits rugged production environments, and can also be deployed in portable, battery ...

Since then, physicists have exploited these non-linear optics in techniques ranging from precision measurement to quantum ...

If the optical gratings are written directly into the fiber ... Once again, a directly inscribed fiber Bragg grating is central to this approach. Thanks to this increase in brilliance, the energy ...
