Full-vectorial mode calculations by finite difference method

Temperature tuning of polarization mode dispersion in single-core and two-core photonic liquid crystal fibers

“…In the work we used our software (vectorial mode solver) in which the full-vector wave equation for two transverse components E x and E y of the propagating electromagnetic field are given in the following form [12] …”

Systematic modal analysis of 3-D dielectric waveguides using conventional and high accuracy nonstandard FDTD algorithms

“…A sufficiently accurate numerical way to overcome this limitation is via computing the -or -field eigenvectors of the vectorial wave equation that takes into account the polarization, vector properties, and discontinuity of the guided modes at the dielectric interfaces, including the corner regions [8]. Upon obtaining the 2-D field distributions in this manner, a proper spatial interpolation is necessary to match the Yee grid.…”

“…2. The associated propagation constant is obtained from the eigenvalue of the wave equation and, for sufficiently small mesh size, the error in its estimation can be made very small (e.g., less than 0.01%) [8].…”

Light Guiding in Low Index Materials using High-Index-Contrast Waveguides

“…We numerically analyzed the performance of the structure shown in figure 1 for guiding and confining light in nanometer-size low index regions. A full-vectorial finite difference mode solver [9] with non-uniform grid mesh was implemented to simulate the quasi-TE eigenmodes of slot-waveguides with different dimensions and wavelengths. For concreteness, we assume that the slot-waveguide is built on the widely used Silicon-On-Insulator (SOI) platform, with the silicon being the high-index material, and the silicon dioxide being the low-index cladding; n H = 3.48, n C = 1.46, and a wavelength of λ 0 = 1.55 µm are assumed, unless otherwise specified.…”
