New Expression for Evaluating the Mean Crosstalk Power in Weakly-Coupled Multi-Core Fibers

Correlation and Power Distribution of Intercore Crosstalk Field Components of Polarization-Coupled Weakly Coupled Single-Mode Multicore Fibres

“…The influence of this assumption on the ICXT statistics is expected to be reduced. This statement is supported by the fact that, when the birefringence effects can be neglected and the depletion of the interfering field is very low, only the random process that models the phase fluctuation induced on the interfered core affects the ICXT field [18]. Additionally, very small differences in the mean ICXT power estimates obtained by numerical simulation results were observed when independent or equal random processes are considered.…”

“…In order to devise mitigating strategies for the effects of ICXT on the performance of WC-MCF systems, several works have proposed ICXT models based on coupled-mode theory and coupled-power theory to evaluate the mean ICXT power and other stochastic parameters related to ICXT [9][10][11][12][13][14][15][16][17][18][19]. Relying on those models, the impact of the ICXT on the performance of different types of OCSs were assessed [20][21][22].…”

“…( 16) may result in a difference of more than 6 dB compared to the rigorous estimation based on Eq. ( 11), especially in the case of a large twisting rate and large correlation length [13]. In Fig.…”

“…(𝑧) was validated by comparing its autocorrelation function obtained by simulation with the theoretical expression of Eq. ( 12) [10], [13]. The random phase noise 𝜙 +!, (𝑧) is applied independently to all cores, i.e., 𝑓 !…”

“…In Ref. [13], a more rigorous analytical expression was reported for evaluating the power coupling coefficient and the averaged XTµ in uncoupled MCFs.…”
