Polarization Conversion Mediated Surface Plasmon Polaritons in Extraordinary Optical Transmission through a Nanohole Arrays
Since Ebbesen's seminal work in 1998 observing extraordinary optical transmission (EOT) through nanohole arrays, much research has focused on the role of surface plasmon polaritons (SPPs) in EOT. While the energy and momentum conditions have become clear, no consensus has been reached on the role …

Narrowband Photodetection in the Short-wavelength Infrared with a Plasmon-induced Hot Electron Device
In gratings, incident light can couple strongly to plasmons propagating through periodically spaced slits in a metal film, resulting in a strong, resonant absorption whose frequency is determined by the nanostructure periodicity. When a grating is patterned on a silicon substrate, the absorption …
