Abstract

Finite-Difference Beam Propagation Method (FD-BPM) in conventional is modified, according to more accurate Helmholtz equation, a new arithmetic is advanced. By using the new arithmetic and the old arithmetic in calculating slab waveguide and calculate the parameter which scales the precision of the method and the calculating time, we prove that the accuracy of the new arithmetic is improved without affecting time performance. At last we calculate the transmission mode in the AWG by the new method to show the practical value of the modified arithmetic.
