Abstract

The numerical method for parameters calculating of the integrated optical elements using a set of Hermitian Bsplines is shown. The method is used to determine the technological parameters of manufacturing Ti:LiNbO3 Xsplitters with a given dividing coefficient. A comparison with experimental data is given.
