註釋This chapter describes how the semiconducting-single-wall nanotube (SWNT) extraction affects their luminescence properties and how such properties can be exploited to fabricate optical sources emitting in near-infrared wavelengths ranging from 1 to 2μm. The main applications of carbon nanotube (CNT) lasers are aimed at optical interconnects and biophotonics. We review recent achievements in obtaining optical gain in thin films doped with CNTs. Techniques for determining optical gain in CNTs are considered with particular focus on the variable strip length (VSL) method and choices to integrate nanotubes in the optical waveguide are discussed.
