COMPUTATION OF OPTICAL CHANNEL WAVEGUIDE WITH ARBITRARY REFRACTIVE INDEX ALLOCATION USING B-SPLINE METHOD
Annotation
The universal strategy of parameters computation for channel optical waveguide with arbitrary refractive index distribution is presented in this work. All calculations are performed from the first principle of reduced wave equation (Helmholtz’s equation). The algorithm is based on the finite elements method using B-splines. Calculation results for channel waveguide with defined index profile and various geometrical configurations are represented as well. The comparison of the obtained results with the results by the known numerical methods is given too in this article.
