Cross-polarized surface lattice resonances in a rectangular lattice plasmonic metasurface
Cross-polarized surface lattice resonances in a rectangular lattice plasmonic metasurface
Multiresonant metasurfaces could enable many applications in filtering, sensing, and nonlinear optics. However, developing a metasurface with more than one high-quality-factor or high-Q resonance at designated resonant wavelengths is challenging. Here, we experimentally demonstrate a plasmonic metasurface exhibiting different, narrow surface lattice resonances by exploiting the polarization degree of freedom …
