The Role of Anisotropy in Few-Mode Optical Fibers

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013
We analyze beating and coupling within LP(1,1) manifold, caused by fiber anisotropy. Results suggest that spinning the fiber may reduce modal dispersion as for nondegenerate LP(0,1) modes of nonideal fibers.

Recent Progress in the Development of Few Mode Fiber Amplifiers [PDF]

Optical Fiber Communication Conference, 2015
We review the performances of both core and cladding pumped few-mode erbium doped fiber amplifiers supporting 6 spatial modes (4 mode groups) which incidentally the highest mode count demonstrated to date.

Rayleigh Backscattering in Few-Mode Optical Fibers

Optical Fiber Communication Conference, 2016
We measure inter-modal Rayleigh backscattering in few-mode optical fibers and compare the experimental results with simulation results obtained from newly-developed analytical formulae. Excellent agreement between theory and experiment allows investigation of mode-coupling dynamics using OTDR.

Analog Transmission over Few-Mode Fibers

Optical Fiber Communication Conference, 2016
Few-mode fibers can increase optical power throughput, arguably the most important parameter that determines the RF gain, noise figure and dynamic range of long-distance analog fiber-optic links.

Few-Mode Fiber Optical Parametric Amplifier

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013
A few-mode fiber with a central depressed index region is designed for few-mode fiber parametric amplification. Such a design allows the zero dispersion wavelengths of both the LP01 and the LP11 modes shifted to the center of the C band. High gain and large bandwidth parametric amplification is demonstrate for both the LP01 and the LP11 modes in a ...

Few-Mode Fiber Devices

Optical Fiber Sensors, 1988
Few-mode fibers provide a number of independent channels in a single strand of optical fiber. Therefore they have potential for increasing channel capacity and data throughput, stabilizing coherent systems, simplifying and miniaturizing fiber optic circuits, and multiplying the number of functions and operations which can be performed.

Investigation of nonlinear effects in few-mode fibers

Photonic Network Communications, 2015
In this work, nonlinear optical effects are exploited for future implementations of space-division multiplexing fiber systems. The paper first presents the fundamentals of intermodal nonlinear phenomena over few-mode fibers, such as cross-phase modulation, four-wave mixing (FWM), stimulated Brillouin scattering and stimulated Raman scattering.

Recent Progress on Multi-Core Fiber and Few-Mode Fiber

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013
This paper reviews research activities concerning multi-core fiber, few-mode fiber and few-mode multi-core fiber. The characteristic of the 12-core fiber that was used for the first 1-Pb/s/fiber transmission experiments is presented.

Investigation of the nonlinearity in few mode fibers

2014 13th International Conference on Optical Communications and Networks (ICOCN), 2014
Nonlinear effects in few-mode fibers (FMF) have been explored in the early years of optical communication. Due to the development of space-division multiplexing (SDM) technology for fiber transmission in FMF, the nonlinearity in FMF has attracted significant research interests recently.
