Generation of Non-Classical Light with Integrated Nanoplasmonic Quantum Interfaces
September 7th, 2017 FRÉDÉRIC PEYSKENS Massachusetts Institute of Technology, Cambridge

A general analytical framework of a nanoplasmonic cavity-emitter system interacting with a dielectric photonic waveguide will be presented. First, the generation of non-classical light from a weak coherent probe beam is discussed. Subsequently, the impact of quenching and dephasing on the single photon generation efficiency and the indistinguishability of photons coupled into the waveguide mode is shown. Our analysis predicts the necessary requirements for non-classical light generation and in particular yields optimal operating conditions to maximize the single photon generation efficiency. Moreover, it is shown that maximizing the efficiency-indistinguishability product requires that the system has to be driven in the weak coupling regime. Our study highlights essential aspects in the physics of integrated nanoplasmonic cavities for quantum photonic applications and identifies all the important design parameters which can guide future efforts in the development of integrated non-classical light sources at both low and room temperature.
