Key results of a benchmark test for integrated optical circuit design by optical field propagation simulation; initiated in 1992 by the Working Group 2 of COST Project 240 at a modelling workshop in Teupitz, Germany, are presented. A great number of algorithms-FFT-BPM, various types of FD-BPM, wide angle approximations, adaptive FE-BPM and MoL-BPM-are compared. The quasi-analytic character of the benchmark tests provides a deeper insight into the absolute accuracy of algorithms.
