Abstract

In the last decade, plasmonic nanoparticles and nanoantennas have enabled unprecedented opportunities to control and guide light at the subwavelength scale [1,2]. They have formed a basis for the development of novel types of advanced plasmonic sensors, solar cells, photo detectors, imaging devices, and nanolasers. Importantly, plasmonic nanoantennas can also provide a convenient way of directional scattering of light into and out of waveguides and, therefore, can also be utilized as a new type of optical couplers [3,4].
