Abstract :
A novel hybrid plasmonic waveguide (HPW) have been numerically investigated, based on a silicon-on-insulator near the telecom wavelength λ= 1550nm by the finite element method. The HPW consist of a metal surface placed on a low index medium (SiO2) which surrounded by a high index medium (Si). With proper waveguide sizes, our proposed HPW can support hybrid long-range surface plasmon which have strong mode confinement (Aeff/A0= 0.5 - 0.7) and long propagation length (L >; 6.5mm) simultaneously.
