Abstract

FIELD OPTICAL MICROSCOPY SINGLE-MODE FIBERS DEVICES LENS
Light confinement to sub-wavelength spot sizes is proposed and realized in tapered optical fibers. To achieve high transmission efficiencies, light propagating along the taper is combined with the excitation of surface plasmon polaritons (SPP) at its tip. (C) 2009 Optical Society of America
