Abstract
The aim of this research is to implement an implicit two step but unconditionally stable numerical scheme which is capable of efficiently solving two-dimensional Helmholtz wave equation in different rib waveguide structures in GaAs material system. In particular, we use alternative direction implicit (ADI) method in combination with successive over-relaxation (SOR) algorithm for optical modal analysis in terms of effective index (or modal index) and normalised index. It is observed that the computed normalised index and modal index exhibit great agreement with other published findings.
