Recombination dynamics of single quantum dots in a fiber system at telecommunication wavelengths

Conference paper
Abstract

Coupling the emitted light from single quantum dots into an optic fiber has been demonstrated as a. plug and play' single-photon Source. In this work, lifetime dynamics measurements were performed with two time-delayed femtosecond optical pulses at different wavelengths. When the energy of the Pumping light is less than the energy of the wetting layer (i.e. quasi-resonant excitation), the single-photon sources can be operated at a speed of 1 GHz.
