Fluorescence enhancement of Er3+-ions using reverse hybrid plasmonic nano-focusing
Conference on Lasers and Electro-Optics(2022)
Abstract
We report the broadband fluorescence enhancement of erbium ions embedded in a single non-resonant reverse nano-focusing waveguide. We measure a large radiative Purcell enhancement of a total emission rate enhancement of > 250 across the entire measured spectrum including the prominent telecoms C-band. Further, we observe the enhancement of single electric dipole transitions from Stark-split levels at room temperature.
