Abstract

Plasmonic antennas have recently received a great deal of attention as building blocks for nanometer scale optical devices, working far beyond the diffraction limit. In this seminar, we will discuss a feasible setup, consisting of linear chains of metallic nano-particles in the proximity of a hetero-interface. By illuminating the system with evanescent waves, the excitation does not interfere with the radiated signal, and thus the radiation pattern of such antennae can be tailored to a greater extent. This can be done dynamically, using external parameters such as the wavelength, polarization and/or angles of the excitation beam. The proposed device can operate therefore as a tunable nanoscopic source of light with high and tunable directionality.
