Extraordinary modulation of light polarization with dark plasmons in magnetoplasmonic nanocavities

Nanophotonics uses light polarization as an information carrier in optical communications, sensing, and imaging. Likewise, the state of polarization of light plays a key role in the photonic transfer of quantum information. In this framework, optical nanodevices enabling dynamic manipulation of light polarization at the nanoscale are key components for future nanophotonic applications.
