Abstract A novel split‐step FFT–BPM is presented for modeling three‐dimensional bends in integrated optic devices. The method is implemented on a unique path‐based 3‐D grid inspired by 2‐D conformal mapping techniques. Improvements in accuracy for the calculation of losses of curved waveguides have been shown over previously reported index modification methods. ©1999 John Wiley & Sons, Inc.
