Ultra-high-Q resonances in plasmonic metasurfaces

M. Saad Bin-Alam et al.

Summary: Plasmonic nanostructures show great potential in ultra-thin sub-wavelength devices, but are often limited by resistive losses. By utilizing surface lattice resonances (SLRs), researchers have achieved a high quality-factor metasurface in the telecommunication band, offering exciting possibilities for manipulating incident light fields and creating flexible wavelength-scale devices.
