Paper Abstract

In this paper, the propagation characteristics of the fields in a planar waveguide, a synchronous-waveguides and a s-bended waveguide were simulated with the Finite Difference Time Domain (FDTD) method. The distribution graphs of the field intensities for the simulated optical waveguides were obtained. Coupling lengths were gained from the data of graphs. By comparing these results with that simulated with beam propagating method (BPM), it is concluded that during simulating waveguide with relatively simple structure the simulation performed by the FDTD method are better in accord with the BPM analysis, but with relative complex structure such as the s-bended waveguide the FDTD method can simulated much better than the BPM dose. So during simulating waveguide with complex structure the FDTD method is the better option.
