Generation of Slow Surface Plasmon Polaritons in a Complex Waveguide Structure with Electric Current Pump

A planar spaser structure composed of semiconducting film and graphene with DC current is proposed and theoretically explored. Graphene possesses velocity of drift current carriers comparable with the phase velocity of surface plasmon polaritons (SPPs) in ultrathin semiconducting film at the teraher...
