Analytical Expression of Average Power-Coupling Coefficients for Estimating Intercore Crosstalk in Multicore Fibers
TL;DR: In this paper, an analytical expression of the average power-coupling coefficient (PCC) based on an exponential autocorrelation function is derived, resulting in no need for heavy numerical computations.
Proceedings ArticleDOI

TL;DR: In this article, the authors demonstrate 1.01-Pb/s transmission over 52 km with the highest aggregate spectral efficiency of 91.4 b/s/Hz by using low-crosstalk one-ring-structured 12-core fiber.
Journal ArticleDOI
Multicore Fiber Technology
Kunimasa Saitoh,Shoichiro Matsuo +1 more
TL;DR: This paper discusses crosstalk estimation in multicore fibers (MCFs) using coupled-mode theory and coupled-power theory, and the combination of MCF and few-mode fiber (FMF), which is FM-MCF, is a very promising approach to realize space multiplicity over 50.
Journal ArticleDOI
Multi-core fiber design and analysis: coupled-mode theory and coupled-power theory
TL;DR: Using the coupled-mode and coupled-power theories, impacts of random phase-offsets and correlation lengths on crosstalk in multi-core fibers are investigated for the first time.
Patent
Multi-core fiber
TL;DR: In this article, a multi-core fiber is formed of two types of cores and in which an effective refractive index difference in a fundamental mode is 0.002 or less in a predetermined range or more.
