The crosstalk of cores shows different diameter dependence although the difference in core parameters is very small. The behavior is explained by taking into account the change of propagation constant caused by the fluctuation in the diameter and the refractive index of cores. The diameter dependence simulated with coupled-power theory shows the same tendency with the measured crosstalk.Institute of Electronics, Information and Communication EngineersJournal Articleapplication/pdfhttp://hdl.handle.net/2115/47174https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/47174/1/IEICEEE8-6_385-390.pdf1349-2543IEICE Electronics Express863853902011-03-25enginfo:doi/10.1587/elex.8.385copyright©2011 IEICEpublisher
