Abstract

We observed up to 200 times fluorescence enhancement inside a tapered silver-plated sub-wavelength pore in comparison with the free space fluorescence. Fluorescence lifetime data was obtained to explore the strong fluorescence enhancement. The mechanism mainly arises from the silver film, the lateral dimensional shape, and size of the waveguide aperture.
