Investigation of crosstalk dependencies on bending radius of heterogeneous multicore fiber

Crosstalk characteristic of heterogeneous MCF with homogeneous A<sub>eff</sub> is investigated. It is experimentally confirmed that radius around which the crosstalk peaks (R<sub>pk</sub>) of smaller than 50 mm is realizable by Δn<sub>eff</sub> of larger than 0.0010.
