Preserving polarization while boosting light from atomically thin semiconductors with silicon nanospheres
Mie resonances overcome the dilemma of signal enhancement versus polarization loss in valley-polarized second-harmonic generation
Release Summary Text: In atomically thin semiconductors, enhancing the frequency-doubled light signal has come at the cost of losing polarization information tied to the valley degree of freedom. Researchers now show that silicon nanospheres can break this dilemma, providing design guidelines for next-generation valley photonic devices.
