| Abstract: | A rigorous mode solver for multilayer fiber configurations using a Constraint Optimization method is presented. For an arbitrary number of dielectric or metallic layers the cylindrical wave equations are solved exactly. The transition between the different layers implies a coupling of all field components. Case examples of three unconventional fiber structures (Air-ARROW-fiber, metal-coated fiber, core to ring fiber coupler) are presented. Mode dispersions charts and field characteristics are calculated to demonstrate the performance of the constraints optimization method applied. |
