Critical Comparison of Three Modal Methods: Bidirectional Eigenmode Expansion, Aperiodic Rigorous Coupled Mode Analysis, and Fourier Series Expansion
Original language description
The performance of three bidirectional modal methods: the "classical" bidirectional eigenmode expansion propagation method, the aperiodic rigorous coupled wave analysis, and the mode expansion method based on harmonic expansion are mutually compared using modeling tasks that include eigenmode calculation of a relatively high-contrast planar waveguide, spectral transmittance of a one-dimensional "photonic crystal" filter in a photonic wire, spectral transmittance of a surface plasmon based optical sensor, and a reflectance from a double-groove structure in a high-contrast waveguide. All methods exhibit generally comparable performance, as follows from good mutual agreement of the results and generally comparable computational time. Although all methodsuse perfectly matched layers as absorbing boundary conditions, their implementation in the aperiodic rigorous coupled wave analysis exhibits significantly stronger attenuation than that used in the other two method
