Abstract
We use a transfer-matrix method (TMM) to investigate light coupling into and out of single-end multimode photonic crystal waveguides. Without multiple-reflection complexity, this approach allows for unambiguous quantitative determination of the coupling efficiency of external light into each guided mode and transition among various guided modes. The TMM can provide a powerful analytical tool to understand and design complex multimode photonic crystal waveguides.Keywords
