Abstract
The modal characteristics of the optical rib waveguides are analyzed systematically based on the effective index method (EIM) and the improved normalized eigen equations of the waveguides are obtained by defined normalized parameters, which the thickness of the outer slab and the normalized outer ridge height of the waveguides are used as parameters in the single-mode condition. The achieved expressions are simpler and easier to optimize the structure parameters in designing a single-mode rib waveguide.
