Efficient light confinement to λ/10 spot sizes in optical fibre
Efficient light confinement to λ/10 spot sizes in optical fibre
Light confinement beyond the diffraction limit has been achieved in optical fibre tips. We successfully fabricated a gold-coated optical fibre tip with wedge-shaped apex for the efficient excitation of surface plasmon polaritons (SPPs). An improved transmissivity higher than 10-2 and spot sizes of the order of λ/10 have been obtained by optimizing the overall light throughput along the fibre tip.

Abstract
Light confinement beyond the diffraction limit has been achieved in optical fibre tips. We successfully fabricated a gold-coated optical fibre tip with wedge-shaped apex for the efficient excitation of surface plasmon polaritons (SPPs). An improved transmissivity higher than 10-2 and spot sizes of the order of λ/10 have been obtained by optimizing the overall light throughput along the fibre tip.
