Mode Properties of Hybrid Plasmonic Waveguide with an Metal Nano-rib
A novel hybrid plasmonic waveguide which consists of a semiconductor nanowire and a mental nano-rib was proposed based on the traditional hybrid plasmonic waveguide.Relationship between the geometrical sizes and the properties of the proposed hybrid plasmonic waveguide, such as effective refractive index, propagation loss and normalized mode area was numerically simulated by employing a finite element method.And the gain threshold of the hybrid waveguide was analyzed.Simulation results reveal that this kind of hybrid waveguide has a low propagation loss and high field confinement ability, and its minimum mode area is only 0.001 52 μm2.
