We propose a novel scheme of surface plasmon polariton (SPP) amplification by stimulated emission of radiation. It is based on a minority carrier injection in an Au/InAs Schottky diode. The proposed amplifier is electrically pumped and has a planar structure. Therefore, it is very compact and can be coupled easily to plasmonic waveguides.
