Abstract :
We propose a plasmonic waveguide through hybrid integration of a gain medium to a dielectric-loaded surface plasmon-polariton (DLSPP) waveguide. The heterogeneous integrated subwavelength plasmonic waveguides (HISPW) provide ultrasmall mode confinement (λ2/210) at the wavelength of 1550 nm, and lossless propagation of surface plasmon-polaritons (SPPs) can be achieved utilizing the optical gain of 420 cm-1 in the InGaAsP nanowire. The strength of SPPs guided in the HISPW can be maintained during propagation through pumping the InGasAsP nanowires.
