This project investigates the performance characteristics of Hollow-core Silicon Nanowires, specially the confinement in each layer of the slot waveguide. In order to undertake such analysis, an accurate and efficient full-vectorial Finite Element Method (FEM) is used to calculate the propagation constant and the modal field profiles of the optical waveguide. The variation of effective indices, effective areas, power density in slot region and the confinement factors of the slot waveguide are rigorous investigated. The modal magnetic and electric field profiles are also presented.
