Abstract: The present disclosure relates to a method of forming a tapered optical fiber, where the optical fiber has a cladding encasing a core and has an initial outer diameter. The method involves applying opposing forces to spaced apart sections of the optical fiber. The spaced apart sections define a length portion representing a waist region. While applying the opposing forces, simultaneously applying heat to the waist region to gradually produce a taper of the optical fiber within the waist region. The taper has a first diameter at a midpoint of the waist region which is less than the initial outer diameter. An etch operation is then performed by chemically etching at least a subportion of the waist region of the optical fiber to reduce the subportion to a second diameter which is less than the first diameter.

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.
