Nanophotonics and plasmonics

Nanophotonics and plasmonics is the study of light at the nanometre-scale. Light can only be focused to a spot roughly half its wavelength in size (a few hundred nanometres for visible light). This limit can be surpassed by coupling light to electrons at the surface of a metal and creating surface plasmons.

    Unidirectional and topological surface plasmon polaritons are currently attracting substantial interest and intense debate. Realistic material models and energy conservation considerations are essential to correctly understand extreme wave effects in non-reciprocal plasmonics, and to assess their potential for novel devices.

    Exciton funnelling due to non-homogeneous strain was previously thought of as an efficient neutral exciton transport mechanism. New findings suggest that exciton funnelling might be negligible compared with another strain-dependent process, the conversion of neutral excitons into trions.
