Mode measurement of few-mode fibers by mode-frequency mapping
Optics Letters, 2018Since 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, 2013The 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), 2013A 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

The Role of Anisotropy in Few-Mode Optical Fibers
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013We 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, 2016We 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.

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.

Analog Transmission over Few-Mode Fibers
Optical Fiber Communication Conference, 2016Few-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.

Investigation of nonlinear effects in few-mode fibers
Photonic Network Communications, 2015In 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.
