MoL-BPM Algorithms for Waveguide Bends and Vectorial Fields,

Abstract

The hitherto used BPM algorithm based on the MoL was first demonstrated at the Hilton Head Conference and than described in. The MoL-BPM overcomes the disadvantages of the BPM based on the paraxial approximation, e.g. small refractive index steps, artificial absorbers, numerical loss. Special characteristics of the MoL-BPM are the use of Helmholtz (or Sturm-Liouville) Equation, numerical absorbing or radiation conditions, use of eigensolution, implementation of the interface conditions for the fields. In this contribution two new algorithms will be presented. First a special algorithm for waveguide bends is presented. Then an algorithm for the vectorial field is described.
