Nanophotonics and plasmonics

Definition

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.

    An external 'tuning knob' by means of applying a transverse electric field has been experimentally demonstrated to modify the bandgap of black phosphorus, making the two-dimensional material practical for integration in functional nanodevices.

    The discrete quantum nature of plasmons may be exploited to make efficient single-photon sources. Despite the losses associated with metallic resonators, advantages over dielectric counterparts exist when it comes to producing efficient quantum emitters.

    High-speed control of polarization may lead to ultrafast modulators and help explore polarization-dependent ultrafast dynamics in matter. Now, femtosecond polarization switching is realized through intraband optical excitation in an ultrathin semiconductor layer.
