Efficient light confinement in optical fibre tapers using plasmonics
Light confinement is limited by diffraction and the ultimate spot size is related to the light wavelength, lambda, and to the refractive index n of the medium where light is being focused. Because of its evanescent wave nature, plasmonics gain a fundamental role in sub-wavelength confinement. In fact plasmons are relatively unaffected by diffraction, can propagate for moderately long distances and can be confined well below the so-called "diffraction limit".

Abstract

Light confinement is limited by diffraction and the ultimate spot size is related to the light wavelength, lambda, and to the refractive index n of the medium where light is being focused. Because of its evanescent wave nature, plasmonics gain a fundamental role in sub-wavelength confinement. In fact plasmons are relatively unaffected by diffraction, can propagate for moderately long distances and can be confined well below the so-called "diffraction limit".
