Modal analysis of waveguides based on a triangular photonic crystal lattice

Abstract

We have performed modal analysis of both conventional single line defect waveguides and proposed "narrowed" waveguides. We have shown that the proposed structure has fewer guided modes than the conventional one, and based on the dispersion diagram-type analysis, we predict that it will have better coupling properties. At present we are working on the experimental verification of these properties. We are also engaged in the quantitative experimental verification of the predicted high transmission efficiency around sharp bends in the photonic crystal waveguides.
