Abstract

This paper presents an efficient search method for equivalent thin film filter realization to a given design under boundary conditions. To calculate realizations, the algorithm presented in [1] is used and the boundary conditions are given in the form of refractive index intervals. Since the number of possible solutions increases exponentially with the number of film layers, only a small part of them can be checked for boundary conditions in a reasonable time. The method presented here uses the results of a Monte Carlo simulation and Yen's algorithm. The time consuming simulation is conducted only once for given boundary conditions. Since the boundary conditions depend on the fabrication process this method saves a significant amount of time during filter design.
