Description
We investigated how nanoemitters randomly distributed in single-walled carbon nanotubes (SWCNTs) can enhance laser emission when excited by plasmon-polariton (PP). We found that when the plasmonic frequency of the carbon nanotubes exceeds a critical value, the plasmon-polariton is macroscopically excited throughout the entire SWCNT. The laser generation time of the nanoemitters is strongly influenced by this plasmonic frequency. This leads to a reconnection of the fields in the nanoemitters and a significant coupling between the emitter radiation and the plasmon-polariton fields. We demonstrated that the resonant change in the spatial field structure is related to an increase in PP excitation, which is evidenced by a strong and narrow peak in the inverse participation ratio of the optical field. This phenomenon has implications for the design of active devices in contemporary nanoelectronics.
