Paper Abstract

Simulation has become central to the successful development of integrated optoelectronic components and devices. Due to its flexibility and ease of use, the Beam Propagation Method, BPM, has established itself as one of the most popular and useful modeling techniques currently available. Many versions of BPM have been explored and presented in the literature with various schemes used to discretize the transverse operator. Vector and wide angled formulations as well as bi-directional schemes have been shown to overcome the inherent scalar, paraxial and one-way propagation assumptions associated with the simpler schemes, consequently expanding the range of practical problems for which BPM is suitable. However, there remain many significant practical scenarios to which BPM currently has limited applicability, for example it struggles to cope with structures in which there are many reflections or with physically large geometries where stringent performance specifications for new designs demand highly accurate 3D simulations. We assess these limitations in comparison with other simulation techniques and consider the major improvements required in the near future.
