In optical communication, isolators are typically used to direct light by applying magnetic fields, ensuring it travels in one direction and preventing interference. The system demonstrated in ...

Scientists build a "metagrating" filter that selects light by both wavelength and angle—unlocking next-gen AR, sensors, and ...

Intrinsic dispersion in periodic systems sets a fundamental bound for independent selectivity of resonant angles and wavelengths. This hinders applications requiring concurrent selectivity of angles ...
