Selective wavelength conversion in a few-mode fiber [PDF]

Optics Express, 2019
We experimentally demonstrate a means to selectively enhance wavelength conversion of WDM channels on a 100 GHz grid exploiting nonlinear effects between the spatial modes of a few mode fiber. The selectivity of parametric gain is obtained by dispersion design of the fiber such that the inverse group velocity curves of the participating modes are ...

Multi-element fiber for space-division multiplexing

, 2013
A novel approach of using multi-element fiber (MEF) technology in space-division multiplexing (SDM) systems is presented. This paper reviews the progress in fabrication and characterization of MEF based both ultra-low crosstalk transmission and amplifier

LCoS-based mode shaper for few-mode fiber

Optics Express, 2013
Spatial light modulation can be used to address specific fiber modes, as required in mode-division multiplexed systems. We theoretically compare phase-only spatial light modulation to a combination of amplitude and phase spatial light modulation in terms of insertion loss and crosstalk for a fiber supporting 11 LP modes.

Mode-division multiplexed transmission with inline few-mode fiber amplifier [PDF]

, 2012
We demonstrate mode-division multiplexed WDM transmission over 50-km of few-mode fiber using the fiber's LP ₀₁ and two degenerate LP ₁₁ modes. A few-mode EDFA is used to boost the power of the output signal before a few-mode coherent receiver. A 6×6 time-

Reach improvement of mode division multiplexed systems using fiber splices [PDF]

, 2013
This letter proposes the introduction of discrete modal crosstalk (XT) through fiber splices for the improvement of the distance reach (DR) of mode division multiplexed (MDM) transmission systems over few mode fibers (FMFs). The proposed method increases

Few-Mode Lensed Fibers

Journal of Lightwave Technology, 2018
Few-mode lensed fiber for focusing multiple spatial modes with minimal distortion are proposed and investigated numerically and experimentally, for the first time to the best of the authors’ knowledge. Although the conventional hyperbolic lens profile works effectively for the fundamental mode, it introduces severe distortion for high-order radial ...
