Enhancement of radiative processes in nanofibers with embedded plasmonic nanoparticles

Efficient manipulation and long-distance transport of single photons is a key component in nanoscale quantum optics. In this Letter, we study the emission properties of an individual light emitter placed into a nanofiber and coupled to a metallic nanoparticle.We find that plasmonic field enhancement together with nanofiber optical confinement uniquely and synergistically contribute to an overall increase of emission rates as well as quantum yields. We predict a quantum yield enhancement up to a factor of 2.5 with respect to free space for an averaged dipole orientation.
