An efficient wavelet-based finite-difference time-domain (FDTD) method was implemented for analyzing nanoscale optical devices.An exemplary dielectric device,a high-index ring resonator,was simulated.Due to the highly linear numerical dispersion properties of this high-spatial-order FDTD,this model achieves significant reduction in the number of cells.i.e.used memory.Furthermore.to solve physical problems with large dimensions.this wavelet-based FDTD model is extended in a parallel computation environment.A mirrored box is analyzed with the parallelized FDTD model.Besides achieving a gain in computation time and memory-saving,the parallel computation result matches the theoretical model.
