Few-mode fibers for mode-division multiplexing

2013 IEEE Photonics Society Summer Topical Meeting Series, 2013
The design of few-mode fibers will be discussed from the point of view of key attributes and fundamental limitations. We will consider the maximum number of modes that might be supported in a practical fiber.

Fabrication of few-mode crystalline core fiber

2013 6th IEEE/International Conference on Advanced Infocomm Technology (ICAIT), 2013
A few-mode crystalline core fiber (FMCCF) cladded by high-index glass is demonstrated. The FMCCF consisted of 38-μm core with YAG single crystal and 260-μm cladding with N-SF57 high-index glass, which was fabricated by drawing-tower and laser-heated pedestal growth techniques. The FMCCF exhibited a V-value below four at 1400 nm to provide five few-mode

CapEx Advantages of Few-Mode Fiber Networks

Optical Fiber Communication Conference, 2015
CapEx minimization for few-mode fiber networks is studied for different traffic patterns for the first time. FMF networks can have significant CapEx advantages for bulk data transfer and for fine-granularity switching by deploying MDM-compatible WSSs.

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.

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.

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.

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 ...

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.
