Semiconducting SWNT extraction was studied using an ultra-centrifugation method assisted by a conjugated polymer. It was demonstrated that the emission intensity can be highly improved and that in some conditions emission from one single nanotube chirality can be achieved. This optimized material was integrated on several photonic structures. The ability of nanotubes to emit light when drop-casted on a silicon waveguide was first demonstrated and its thermal stability was further investigated. We concluded over interesting integration ability on Silicon-On-Insulator (SOI) substrate, with coupling efficiency up to the order of 10%. The integration of SWNT on Bragg mirrors based cavity was also investigated. This is the first milestone towards a carbon nanotube based fully integrated LASER.
