Abstract

<span style="font-size: 10pt; font-family: 'Arial','sans-serif'">In this Letter, we propose a hybrid plasmonic nanosystem consisting of a silver cladding layer with a semicylinder bump on top of InGaAsP nanowire. Because of the coupling between the dielectric waveguide mode and surface plasmon polariton mode, the hybrid plasmonic mode can exhibit low loss with strong field localization. The finite element method numerical simulations are employed to evaluate the performances of the hybrid mode. In order to achieve the lossless propagation of the hybrid mode with the mode area of 0.0058(lambda(2)/4) at 1.55 mu m, the material gain of 200 nm x 300 nm InGaAsP nanowire should reach 1223 cm(-1). </span>
