W pracy przedstawiono teoretyczne podstawy metody dekompozycji kierunkowej oraz omówiono jej zastosowanie do analizy i projektownia urządzeń optycznych i optoelektronicznych realizowanych metodami technologii światłowodowej planarnej. W szczególności zaś przedmiotem rozważań są podukłady planarnych struktur światłowodowych stosowane w układach optyki zintegrowanej, takie jak światłowód przewężany,...
A novel formulation of tapered beam propagation algorithm is given. The new algorithm is tested on standard taper structures in order to check the accuracy, reciprocity and the convergence rate. It is shown that the new algorithm preserves the advantages of the previous formulation while being easier to implement and requiring less computation per one propagation step. The results obtained by the...
