Paper Abstract

The integration of Plasmonic Nano-Resonators (PNRs) to optical fibers tips with thin metallic claddings forming plasmonic slot nano-resonators (PSNRs) is presented. It is shown that the placement of the PSNR at the cut-off radius of the fiber tip for a specific wavelength where the group velocity tends to zero and light slows down leads to an optimization of field's enhancement. Enhancement factors greater than 3x105 were calculated through Finite Element Method (FEM) simulations by placing the PSNR at the cut-off radius and by changing the geometrical characteristics in order to identify optimal conditions for loss minimization that can find many practical applications in nano-optics and sensing.
