Study on Characteristics of Coupled-Core Four-Core Fibers With Different Core Pitches

IEEE Photonics Journal
We studied the characteristics of coupled-core four-core fibers (CC-4CFs) with different core pitches both theoretically and experimentally. The spatial mode dispersions of different fibers were analyzed, and the result agrees well with theoretical ones.

Multidimensional Bit-Wise Sparse Decoding for Residual IC-XT Mitigation in Optical Long-Haul CC-MCF Links

IEEE Photonics Journal
Coupled-core multicore fiber (CC-MCF) transmissions rely on sufficient taps of multiple-input and multiple-output (MIMO) equalizers which should cover the channel temporal pulse response raised by the elevated spatial mode dispersion of fibers. Otherwise,

Temperature and vector bending sensing with a supermode fiber Bragg grating

JPhys Photonics
Due to their multiple advantages, single-mode fiber Bragg gratings (FBGs) are widely used in a myriad of practical sensing applications. However, their concurrent sensitivity to strain and temperature makes a reference sensor necessary in several ...

A New Algorithm to Mitigate Fragmentation and Crosstalk in Multi-Core Elastic Optical Networks

Photonics
This paper proposes a core and spectrum allocation algorithm for elastic optical networks based on multi-core fibers. In this context, the fragmentation and crosstalk mitigation algorithm (FraCA) is proposed.
