Temperature-tunable Surface Lattice Resonances in Plasmonic Metasurfaces

Metamaterials are artificial structures exhibiting properties not found in nature, such as negative refractive index [1] , [2] . Recently, metasurfaces that consist of periodically organized metal nanoparticles, and therefore exhibit collective responses known as surface lattice resonances (SLRs), h...

More Information
Summary:Metamaterials are artificial structures exhibiting properties not found in nature, such as negative refractive index [1] , [2] . Recently, metasurfaces that consist of periodically organized metal nanoparticles, and therefore exhibit collective responses known as surface lattice resonances (SLRs), have attracted considerable attention [3] . They are often associated with high quality factors (Q~100) and are subsequently associated with considerable local-field enhancements that boost the occurring light-matter interactions [4] , [5] . However, little work yet exists on active SLR-based structures, that would permit modification of their optical properties via external means and facilitate emergence of novel SLR-based applications.
