TRENCH ASSISTED MULTI-CORE FIBER WITH LARGE AEFF OVER 100 ΜM2 AND LOW ATTENUATION LOSS
Katsunori Imamura1, Kazunori Mukasa1, Ryuichi Sugizaki1; 1Fitel Photonics laboratory, Furukawa Electric co., Ltd., Japan.
 By applying trench index profile, we successfully developed multi-core fibers with large Aeff over 100 μm2 and attenuation loss as low as 0.2 dB/km at 1550 nm. The low cross-talk properties were also confirmed.

 The cladding-thickness of trench-assisted multi-core fibres was investigated in terms of excess losses. The MCF with an effective area of 110 µm2 at 1.55 µm and 181-µm cladding diameter was realised without any excess loss.

MICROBENDING-INDUCED CROSSTALK INCREASE IN HETEROGENEOUS MULTI-CORE FIBER
Tetsuya Hayashi1, Takashi Sasaki1, Eisuke Sasaoka1; 1Optical Communications R&D Laboratories, Sumitomo Electric Industries, Ltd., Japan.
 Inter-core crosstalk of a heterogeneous multi-core fiber was experimentally observed to increase more than 10 dB by applying microbending to the fiber. The increase was described theoretically based on bending-radius dependence of the crosstalk.

CROSSTALK IN MULTI-CORE OPTICAL FIBRES
John M. Fini1, Benyuan Zhu1, Thierry Taunay1, Man Yan1, Kazi Abedin1; 1OFS Laboratories, USA.
 Achieving low crosstalk and high core density is one of the key challenges for multicore fibre. Advanced low-crosstalk designs aim for optimal mode confinement and additional phase-mismatch suppression robust to variations.

MULTI-CORE FIBER DESIGN AND ANALYSIS
Masanori Koshiba1, Kunimasa Saitoh1, Katsuhiro Takenaga2, Shoichiro Matsuo2; 1Hokkaido Univ., Japan; 2Fujikura, Japan.
 Impacts of random phase offset in coupled-mode theory and autocorrelation function in coupled-power theory on crosstalk of multi-core fibers are investigated for the first time. Simulation results are in good agreement with measurement results.
