Abstract

A multiresolution time-domain (MRTD) method based on Daubechies scaling functions is proposed for the time-domain analysis of planar optical waveguide devices. The anisotropic perfectly matched layer absorbing boundary condition is implemented for the MRTD method. The proposed scheme is used to model the parallel-slab directional coupler, and the simulation results are in good accord with the analytical solutions. Compared with the standard finite-difference time-domain method, this scheme can save considerably computer resources without loss of accuracy.
