Elaboration of Methods and Algorithms of Calculation of Main Characteristics of Three-Dimensional Irregular Integrated-Optical Waveguides

In the present paper the methods and algorithms permitting to calculate fields for various directed and radiant TE and TM modes of symmetrical and asymmetrical integrated-optical waveguides are presented. The description of the theoretical approaches and algorithm of calculation of the field of a scattered radiation outside of an irregular integrated-optical waveguide in the system of visual programming Delphi is given. The dispersion dependences for TE and TM modes in the trigonometric form, and appropriate pictures of fields of the radiation TE modes of the substrates and the pictures of fields of electromagnetic radiation scattered in an integrated-optical waveguide with three-dimensional irregularities are also given.
