Description
Summary:Carbon nanotubes are a telecom band emitter compatible with silicon photonics, and when coupled to microcavities, they present opportunities for exploiting quantum electrodynamical effects. Microdisk resonators demonstrate the feasibility of integration into the silicon platform. Efficient coupling is achieved using photonic crystal air- mode nanobeam cavities. The molecular screening effect on nanotube emission allows for spectral tuning of the coupling. The Purcell effect of the coupled cavity-exciton system reveals near- unity radiative quantum efficiencies of the excitons in carbon nanotubes. Keywords: carbon nanotubes, silicon photonics, microcavity, cavity quantum electrodynamics, Purcell effect
