The Transmission Properties of Hybrid Ridge Plasmonic Waveguide with A Gain Medium Layer
摘要
Abstract
A novel hybrid ridge plasmonic waveguide with a gain medium layer is presented based on the traditional ridge waveguide. Dielectric layer in the hybrid ridge plasmonic waveguide contains two parts; the first part is a single dielectric area and the second part is a double-layers ridge area containing two kinds of dielectric. The 2D-FDTD method is used to analyze transmission characteristics of the waveguide structure. The electric field distribution of TM mode is given. The dependence of output power and transmission loss on structural parameters and refractive index are discussed. The results show that the transmission loss is up to with the help of the gain medium. The waveguide structure can be applied to the research and fabrication of optical integrated chip.关键词
