Abstract

We consider theoretical models of the nanolaser and logic gates on carbon nanotubes (CNTs). In our work, it is shown at pumping the nanoresonator of the nanolaser on CNT by optical radiation using a quantum dot as nano light emitted diode (LED), the coherent flow of surface plasmon-polaritons arises when the generation threshold is exceeded. The coherent plasmonic flow from the partially reflecting mirror of the nanolaser enters the attached CNT plasmonic waveguide. Plasmonic logic gates NOT and OR based on CNTs represent the complete functional basis for binary logic. The proposed nanolaser and logic gates on CNTs can be used in plasmonic circuitry in the telecommunication frequency band.
