Such devices are of interest for the conversion of fast electrical signals into optical ones within a nanophotonic circuit. Here, we demonstrate that waveguide-integrated single-walled CNTs are promising high-speed transducers for light-pulse generation in the gigahertz range. Using a scalable fabrication approach we realize hybrid CNT-based nanophotonic devices, which generate optical pulse trains in the range from 200 kHz to 2 GHz with decay times below 80 ps. Our results illustrate the potential of CNTs for hybrid optoelectronic systems and nanoscale on-chip light sources. %K carbon nanotubes %K CNT %K infrared %K integrated optics devices %K nanomaterials %R 10.3762/bjnano.8.5 %U http://www.ncbi.nlm.nih.gov/pubmed/28144563 %U https://doi.org/10.3762/bjnano.8.5 %P 38-44
