摘要：An apparatus for enhanced light transmission is provided. The apparatus
comprises a metal film having a first surface and a second surface, at least one apertureprovided in the metal film and extending from the first surface to the second surface, anda periodic surface topography provided on at least one of the first and second surface ofthe metal film. Light incident on one of the surfaces of the metal film interacts with asurface plasmon mode on at least one of the surfaces of the metal film therebyenhancing transmission of light through the at least one aperture in the metal film. Theapparatus may have a single aperture or a plurality of periodically arranged apertures.Wavelength-selective optical filters, spatial optical filters, light collectors, near-fieldscanning optical microscope probes and photolithographic masks are also provided.
