Intercore crosstalk in direct-detection homogeneous multicore fiber systems impaired by laser phase noise [PDF]
Optics Express, 2017 The impact of the laser phase noise on the photodetected intercore crosstalk and performance of direct-detection orthogonal frequency division multiplexing multicore fiber systems is experimentally investigated. A new solution to overcome the performance

Resource Allocation in Multicore Elastic Optical Networks: A Deep Reinforcement Learning Approach
Complexity, 2023 A deep reinforcement learning (DRL) approach is applied, for the first time, to solve the routing, modulation, spectrum, and core allocation (RMSCA) problem in dynamic multicore fiber elastic optical networks (MCF-EONs).

Impact of Intercore Crosstalk on Achievable Information Rates [PDF]
2018 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2018 We investigate the impact of intercore crosstalk in a 7-core fiber on signal to noise ratio and achievable information rates for PDM-QPSK, PDM-16QAM, and PDM-64QAM formats.

Performance of adaptive DD-OFDM multicore fiber links and its relation with intercore crosstalk
Optics Express, 2017 Adaptive direct-detection (DD) orthogonal frequency-division multiplexing (OFDM) is proposed to guarantee signal quality over time in weakly-coupled homogenous multicore fiber (MCFs) links impaired by stochastic intercore crosstalk (ICXT). For the first time, the received electrical power of the ICXT and the performance of the adaptive DD-OFDM MCF link

Effect of core-dependent loss on the intercore crosstalk in multicore fiber systems with concatenated random loss fiber segments [PDF]
2023 23rd International Conference on Transparent Optical Networks (ICTON), 2023 We investigate the impact of core-dependent loss (CDL) on the signal and crosstalk (XT) powers at the output of a link composed by several concatenated multicore fiber (MCF) segments, by considering random CDL in each MCF segment.

Optics Express, 2013 We have derived an intuitively interpretable expression of the average power-coupling coefficient for estimating the inter-core crosstalk of the multicore fiber. Based on the derived expression, we discuss how the structure fluctuation and macrobend can affect the crosstalk, and organize previously reported methods for crosstalk suppression.
