Semiconducting single wall carbon nanotubes (s-SWCNTs) are promising room-temperature telecom-band nano-emitters that could be integrated in silicon photonic circuits for the realization of on-chip optical sources. We report here the integration of a large quantity of s-SWCNTs as an active cladding layer on top of silicon micro/nano cavities. The gathered results show that the luminescence of the SCNTs can be efficiently coupled into the considered photonic crystal cavity modes, which exhibits a clear spectral narrowing as a function of the pump power. These results constitute an important step towards the realization of a carbon nanotube optical source integrated into the silicon platform.
