In this article, the deviations from the group delays expected for the optimum power-law index profile are numerically calculated for several types of undesired fibers using a scalar multilayer approximation method.Abstract:
The deviations from the group delays expected for the optimum power-law index profile are numerically calculated for several types of undesired fibers using a scalar multilayer approximation method. This paper shows the way two fibers are selected from among undesired fibers so that the fiber spliced to each other becomes broad band.read more

Few-Mode Fibers for Mode-Division-Multiplexed Systems
TL;DR: In this paper, the design trade-offs that are at stake when optimizing few-mode fibers (FMFs) that support a high number (ge$ 6) of LP modes are described.
Proceedings ArticleDOI
Low-DMGD 6-LP-Mode Fiber
TL;DR: The design and the fabrication of a low-DMGD 6-LP-mode fiber adapted to strongly-coupled mode-division-multiplexed systems that allows to multiply the capacity by a tenfold factor is reported.

Multimode fibers for compensating intermodal dispersion of graded-index multimode fibers
TL;DR: In this article, the authors proposed a novel type of multimode dispersion compensation fiber (MM-DCF) by which the intermodal dispersion of multimodal fibers (MMFs) can be effectively compensated.

Multimode fiber link dispersion compensator
TL;DR: In this paper, a dispersion compensated multimode waveguide fiber link is described, where the dispersion of essentially any wavelength can be compensated by adding a compensating waveguide to the link, the compensated waveguide having a profile shape and a.lambda.p wavelength which counters dispersion caused by the original waveguide.

Pierre Sillard,Denis Molin,Marianne Bigot-Astruc,Koen De Jongh,Frank Achten,Jose Enrique Antonio-Lopez,Rodrigo Amezcua-Correa +6 more
TL;DR: In this paper, the micro-bend-resistant low-differential-mode-group-delay (low-DMGD) few-mode fibers that support up to six mode groups (12 LP modes, 21 spatial modes) and that are adapted to multiple-input multiple-output mode-division-multiplexed transmissions are presented.

Numerical Analysis of Pulse Broadening in Graded Index Optical Fibers
TL;DR: In this article, a scalar multilayer approximation method for calculating the impulse response of multimode optical fibers from measured refractive-index profiles is described, and a comparison is made between shapes of measured pulses and calculated pulses.
Journal ArticleDOI
Multipath time dispersion theory of an optical network
TL;DR: A model for the analysis of the bandwidth along an optical transmission line is suggested and tested and it is found that optical equalization is a real effect that has been observed in practice and is affected by only two major factors.

On Wave Propagation In Inhomogeneous Media
TL;DR: In this article, the authors generalized the relationship between phase and group velocity for wave propagation in homogeneous media to the inhomogeneous case and used the stationary property of the frequency as a functional function of the wave function.

Mode properties and dispersion for two optical fiber-index profiles by the propagating beam method.
Michael D. Feit,J. A. Fleck +1 more
TL;DR: The propagating beam method generates solutions for the electric field in a graded-index optical fiber that emphasize beam characteristics rather than modal properties and leads to the conclusion that fiber bandwidth cannot be accurately inferred from rms pulse dispersion.

Determination of mode power distribution in a parabolic-index optical fibers: Theory and application
TL;DR: In this paper, a measurement method for determining mode power distribution in a multimode parabolic-index fiber is developed, where the mode power distributions are obtained in terms of the principal mode number by numerically processing the measured Fraunhofer diffraction patterns of the near-field patterns on an output fiber endface.
