Extended dynamics and lasing of nanoemitters enhanced by dispersing single-walled carbon nanotubes

•Incorporation of dispersed carbon nanotubes (CNT) in the working space of nanoemitters considerably changes the properties of the plasmon-polariton fields in such a hybrid system.•The field emission increases significantly if the plasma frequency of CNT exceeds the critical frequency and PP are generated macroscopically throughout the system.•The strength of coupling of nanoemitter with plasmon-polaritons is maximal when the field interconnections appear in the entire carbon nanotubes array.•The results are interesting for the design of active devices of modern nanotechnology allowing control and miniature low threshold coherent sources with tunable polarization.
