Paper Abstract

Metasurfaces consisting of periodically arranged plasmonic nanoparticles could become a promising platform for optical filtering and nonlinear experiments. However, due to the high absorption loss of noble metals e.g. gold, the localized surface plasmon resonances (LSPR) of individual nanoparticles exhibit very low quality factors (Q ~ order of 10), which is not suitable for practical usage. Here, we experimentally demonstrate a plasmonic metasurface with ultra-high-Q (above 1000) surface lattice resonances (SLRs) around the optical telecommunication wavelength of 1550 nm by optimizing the LSPR of rectangular gold nanoparticles and the overall array size.
