The role of plasmonic resonances on the performance of nanoantennas and the influence of geometrical parameters imposed by nanofabrication are discussed.Abstract:
Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light with nanoscale matter by their ability to efficiently link propagating and spatially localized optical fields. This ability unlocks an enormous potential for applications ranging from nanoscale optical microscopy and spectroscopy over solar energy conversion, integrated optical nanocircuitry, opto-electronics and density-of-states engineering to ultra-sensing as well as enhancement of optical nonlinearities. Here we review the current understanding of metallic optical antennas based on the background of both well-developed radiowave antenna engineering and plasmonics. In particular, we discuss the role of plasmonic resonances on the performance of nanoantennas and address the influence of geometrical parameters imposed by nanofabrication. Finally, we give a brief account of the current status of the field and the major established and emerging lines of investigation in this vivid area of research.read more

Plasmonic Optical Nanoantennas
TL;DR: In this paper, the authors provide an overview of the recent design, fabrication, and characterization efforts on plasmonic antennas, and show that it is possible to apply familiar radio-frequency concepts to model and design optical nanoantennas, and use these powerful design tools to predict the linear and nonlinear response of plasmoric nano-antenna designs for all-optical communications and signal processing.
