Effective index method for generalised waveguide dispersion characteristics analysis of optical channel waveguides

An approximate analysis of the generalised waveguide dispersion characteristics (GWDC) of optical channel waveguides based on the effective index (EI) method is presented. As an illustration of its practical applications, the possibility of achieving temperature-independence in glass rib waveguides is studied and predicted for the first time which may have important applications for integrated-optic devices requiring temperature-stabilised operations.
