Nano-optics: Optical antennas tuned to pitch
Lukas Novotny1
Abstract
Mapping out the resonant modes of optical antennas is part of a largely unexplored terrain — but not any more, as a study that applies a luminescence technique to gold antennas demonstrates.
Optical antennas are devices designed to efficiently convert optical radiation into localized energy, and vice versa. They enhance the interaction between light and matter, and hence have the potential to boost the efficiency of optoelectronic devices ranging from light-emitting diodes to solar cells.
