Abstract

We studied the loss compensation of surface plasmon polaritons (SPPs) with InGaAsP quantum wells at telecom wavelength. The quantum wells are buried in the vicinity of a thin Au film. The propagation length of short-range SPPs increases drastically with the gain coefficient of quantum wells, generated by a forward bias. The elongation of SPP propagation is experimentally observed via long-range SPPs, which strongly couple with the short-range SPPs. This study paves a way for electrically manipulated amplification of SPPs in plasmonic circuits.
