Abstract

In this study, we propose a simple and applicable approach to analyze the large angle (larger than 10°) abrupt bent waveguides. By using the conformal mapping technique, the abrupt bent waveguide is transformed into an equivalent straight one which the conventional (paraxial) beam propagation method (BPM) can be applied to analyze it directly. The Held distribution in a 20° microprism type abrupt bent waveguide is also demonstrated by our method.
