More on the iteration of the beam propagation method for analyzing Bragg gratings.
The mathematical foundation of the iteration of the beam propagation method is described in this paper. Detailed analytical analyses are presented. These analyses explain further how the iteration of the beam propagation method works, and provide the reason why it works. Some additional comments are also presented on the formulation and practical implementation in analyzing Bragg gratings in different situations.
