Abstract
In this paper, a simple finite difference beam propagation method (FDBPM) involving the fourth-order Runge-Kutta algorithm (RKBPM) is proposed to analyze 2-D and 3-D optical waveguides. We compare the accuracy and computational efficiency with those of the conventional FDBPM employing the Crank-Nicholson method (CNBPM). The simulation results have demonstrated that the RKBPM is a superior technique to the CNBPM and complicated patterns of photonic circuits, based on bent waveguides, can be designed by the RKBPM.
