Coupled surface plasmon–phonon polariton nanocavity arrays for enhanced mid-infrared absorption

Coupled surface plasmon–phonon polariton nanocavity arrays for enhanced mid-infrared absorption

Resonant optical cavities are essential components in mid-infrared applications. However, typical film-type cavities require multilayer stacks with a micron-thick spacer due to mid-infrared wavelengths, and their performance is limited by narrow frequency tunability and angular sensitivity. We propo...
