Abstract
The possibility of surface plasmon polaritons (SPPs) amplification and generation in a waveguiding system containing single-walled carbon nanotube (CNT) and dielectric substrate is investigated. The SPP amplification is created by applying direct current in the CNT. Using numerical simulation, the effect of the substrate on the SPP characteristics in CNT was studied and it was shown that for a substrate with a high refractive index, the SPP amplification is realized at a lower drift velocity of free carriers of the pump current. For realization of the feedback in the CNT it is proposed to use the substrate with a periodic modulation of the dielectric function.
