摘要
Accurate solutions of complex modes in leaky waveguides grown on low-cost silicon substrates are presented by using two rigorous numerical methods incorporating vectorial approaches. The optimisation of waveguide parameters to restrict modal loss within a given limit and the study of mode filtering for multimode optical waveguides is also presented.
