Abstract
A nanoscale structure fabricated on a planar end facet of an optic fiber is described, to enable detection of molecules by surface-enhanced Raman scattering. The nanoscale structure may comprise an array of nanopillars. The nanoscale structure may also comprise a non periodic, or random, surface-relief structure. The nanoscale structure may be coated in a metal, comprising, for example, silver, gold, aluminum, iridium, platinum, palladium, copper, or a combination of the same. The nanoscale structure may be fabricated on a planar end facet of an optical fiber by interference lithography.
