Considerable improvement in accuracy over the paraxial approximation is achieved with virtually no additional computation. In the present algorithm, the quadratic element, transparent boundary condition, adaptive reference index, and adaptive grid are effectively utilizedIEEEJournal Articleapplication/pdfhttp://hdl.handle.net/2115/7376https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/7376/1/IPTL8_9.pdf1041-1135IEEE Photonics Technology Letters89120812101996-09enginfo:doi/10.1109/68.531838©1996 IEEE.
