Abstract
We present a hill-shaped refractive index (HS-RI) structure in 16-core fiber that can provide 160 channels for the transmission system. The HS-RI mainly settles the issue of the large inter-mode crosstalk (IMXT) between LP 21 mode and LP 02 mode. We obtain the optimized parameters using the finite element method. Numerical analyses reveal that the inter-core crosstalk (ICXT) of all modes is smaller than −30dB/100km in the C band, and the effective mode refractive index difference (Δ n eff ) is more than 1×10 −3 . The minimum effective mode field area can achieve 89.80µm 2 , which greatly reduces the nonlinearity of fiber. The max dispersion is 15.59ps/(nm∗km), which can greatly guarantee signal quality in the transmission process. he relative core multiplexing factor (RCMF) can reach 65.81, which realizes the high space division multiplexing rate. The proposed fiber can be applied to a space division multiplexing system to enhance the fiber transmission channels and capacity.
