Enhancing carbon-nanotubes luminescence with the help of plasmonic antennas
Résumé
Due to their 1-Dimensional character semi-conducting carbon nanotubes are fascinating light sources. They radiate in the telecommunication-wavelengths range with well-defined exciton peaks even at the temperature room. Unfortunately they are not bright sources because of a small quantum yield. Increasing the radiative rate is necessary to make a single carbon-nanotube an attractive single-photons source at the telecom wavelengths. Such an increase may be realized by engineering the electromagnetic environment that leads to the well-known Purcell effect. In this talk we present our strategies to increase the luminescence rate of single carbon-nanotubes with the help of plasmonic antennas. We report an exaltation of the luminescence by a factor 200.
