In this paper, we first review and compare the two main techniques allowing to purify and extract selectively semiconducting single-walled carbon nanotubes (s-SWNT)). These purification steps are essential to obtain an optical-quality material. Such material is then suitable for optical applications and photonic devices. We present two major advances in carbon nanotubes optics and photonics: on one hand, the demonstration of optical gain in s-swnt by two independent methods, with modal gain as high as 160 ±10 cm-1 at 1.3 μm and on the other hand, the integration of SWNT in silicon-on-insulator (SOI) platform as a potential material for integrated photonic devices. Overall coupling efficiency could be estimated up to 10-1.
