Controlling light emission

Scattering and propagation at the nanoscale with metal

José A. Sánchez Gil – Instituto de la Materia CSIC

Controlling light emission, scattering and propagation at the nanoscale with metal, semiconductor and hybrid nanowires.

We overview a variety of configurations of interest in Nanophotonics that exploit the resonant optical properties of metal, semiconductor and hybrid nanowires, to control light emission, scattering and propagation at the nanoscale. First, we investigate photoluminescence from finite semiconductor nanowires, theoretically and experimentally demonstrating their behavior as efficient optical nanoantennas, with directio nal emission of polarized light given by the material and also by the nanowire geometry and dimensions.
