Abstract
Quantum optics applications rely crucially on the control and long range transport of single-photons. We investigate how embedding a metal nanoparticle with an optical emitter in a fiber modifies the emission properties of the emitter. By coupling the light emitter to a metal nanoparticle, we show that the emission rates, Purcell factor and quantum yield are increased due to the combined effects originating both from the confinement in the fiber and from the nanoparticle's plasmonic enhancement. We simulate numerically a fiber of permittivity ε = 4 containing a silver nanoparticle of radius 30 nm and find that the quantum yield enhancement can be up to 2.5 larger than in free space.
