Analytical Formulation of Supermodes in Multicore Fibers With Hexagonally Distributed Cores

IEEE Photonics Journal, 2015
The supermodes in 19-core multicore fibers (MCFs) with identical hexagonally distributed cores are analyzed in detail by using the coupled mode theory and matrix operation.

A Numerical Assessment of the Effect of Concatenating Arbitrary Uncoupled Multicore Fiber Segments on Intercore Crosstalk in Long-Haul Communication Links

Photonics
Random core dependent loss (CDL) has been shown to increase the direct average intercore crosstalk (ICXT) power in long-haul uncoupled multicore fiber (MCF) links.

Fiber link stabilization with a multicore fiber amplifier

Optics Letters
We study the use of separate cores of a multicore erbium-doped fiber amplifier (MC-EDFA) in a noise-canceled link for ultrastable optical frequency transfer. We demonstrate fractional frequency instability of 5×10 −19 at 1000 s averaging time for the stabilized MC-EDFA alone and 1.4×10

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 ...
