This conference talk will sum up our recent contributions related to the integration of semiconductor carbon nanotubes (s-SWNTs) as an active material in silicon photonics. This work is motivated by the possible use of s-SWNTs for light emission, detection, and modulation relying on the same hybrid on-silicon integration platform. We will first describe experimental results carried out to prepare high quality thin polymer layers doped with purified s-SWNTs. Our efforts to integrate this effective active material in silicon photonic resonators and nanocavities will be then described. We report cavity enhanced near infrared emission from nanotubes accompanied with a spectral narrowing effect when increasing pumping power levels and a threshold-like behavior regarding device light emission.
