Description
Summary:A Legendre pseudospectral frequency-domain (PSFD) method incorporated with stretched coordinate perfectly matched layers (PMLs) and a multidomain technique is established for solving optical waveguide leaky modes. A recently developed penalty scheme is employed to assure numerical accuracy. This high-accuracy solver is used to analyze a leaky six-air-hole microstructured fiber, for which self convergence of accuracy in calculated effective indexes is demonstrated to be on the orders of 10 -14 . Then, the photonic wire is analyzed and the comparison with the analysis results from other methods is discussed.
