Abstract

This paper overviews the most recent advances in the unstructured Transmission Line Modelling method that is uniquely placed for modeling advanced photonic applications with multi-scale features. The paper focuses on the holistic approach that needs to be taken when considering these applications which involves not just the electromagnetic solver, but also important aspects of the unstructured mesh generation and geometry definition. The capability of the UTLM is demonstrated on the complex geometry of a photonic polarization splitter that incorporates diverse components namely tapers, multimoded waveguides and a photonic crystal region.
