Waveguide-Integrated Light-Emitting Carbon Nanotubes


  • The authors contributed equally to this work.



We demonstrate how light from an electrically driven carbon nanotube can be coupled directly into a photonic waveguide architecture. Waferscale, broadband sources are realized integrated with nanophotonic circuits allowing for propagation of light over centimeter distances. Moreover, we show that the spectral properties of the emitter can be controlled directly on chip with passive devices using Mach-Zehnder interfero­meters and grating structures.
