As a result, the MCFs with large Aeff over 100 μm2 and low micro bending loss were successfully fabricated. The results indicate the importance of fiber design to realize large Aeff MCFs including fiber diameters, which largely affect the micro bending loss property. Additionally, MCF with large Aeff, low attenuation loss and suppressed cross-talk was successfully realized by optimizing the fiber design. The cross-talk properties could be estimated by the simulation based on the coupling power theory taking the influences of the longitudinal fluctuation of core diameter into account.Optical Society of AmericaJournal Articleapplication/pdfhttp://hdl.handle.net/2115/45610https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/45610/1/OE19-11_10595-10603.pdf1094-4087Optics Express191110595106032011-05-23enginfo:doi/10.1364/OE.19.010595©2011 Optical Society of Americapublisher
