Abstract: Polarization converter is firstly proposed with the functions of simultaneously converting a linear polarization (LP) and a circular polarization (CP) to its corresponding cross ...

As fast as modern electronics have become, they could be much faster if their operations were based on light, rather than ...

Engineers have developed a multifunctional, reconfigurable component for an optical computing system that could be a game changer in electronics.

Abstract: A study on non-Hermitian physics via metasurfaces always requires tuning the gain or loss term in a coupling system to observe singularities. But the structures of passive metasurfaces are ...
