Abstract

We have studied plasmonic slot nanoresonators (PSNRs) embedded in a gold-coated microfiber. Light is coupled from the plasmonic waveguide into the PSNR, showing strong localization in three dimensions. Single bow-tie and rectangular PSNRs, as well as cascades of multiple bow-tie PSNRs, have been considered. The intensity enhancement and the resonance wavelength depend on both the PSNR and microfiber dimensions. The PSNRs embedded in plasmonic microfibers could find wide range of applications, such as surface enhanced Raman scattering, optical filtering, bio-sensing, and spectroscopy.
