DOI: 10.1021/acsphotonics.8b00447
Abstract: Illuminating a plasmonic nanoantenna by a set of coherent light beams should tremendously modify its scattering, absorption, and polarization properties, thus, enabling all-optical dynamic manipulation. However, diffraction inherently makes coherent control of isolated subwavelength-sized nanoantennas… read more here.
