Efficient sub-wavelength light confinement using surface plasmon polaritons in tapered fibers.
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.
