Few-mode fiber transmission with in-line few-mode erbium-doped fiber amplifier

SPIE Proceedings, 2013
We demonstrate wavelength-division multiplexed (WDM) and mode-division multiplexed (MDM) transmission over a fiber recirculating loop comprising of a 25-km span of low differential mode group dispersion (DMGD) few-mode fiber carrying the LP01 and LP11 mode groups, and an inline few-mode erbium-doped fiber amplifier (FM-EDFA) providing low mode ...

Mode measurement of few-mode fibers by mode-frequency mapping

Optics Letters, 2018
Since few-mode fibers (FMFs) have great potential as the new transmission media for optical communications, the ability to distinguish different fiber modes is essential. Most of the traditional schemes do not yield phase information, or are limited by beam size and mechanical requirements.

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.

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.

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.

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.

Weakly-coupled Few-Mode Fibers and their Applications

2017 European Conference on Optical Communication (ECOC), 2017
We present design strategies for weakly-coupled few-mode fibers and their representative applications in passive optical networks, interconnects for datacenters and transmission of analog signals.

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.

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
