Characterization of few mode fibers by OLCI technique [PDF]
2014 The European Conference on Optical Communication (ECOC), 2014 All LP modes of a few mode fiber are simultaneously characterized using phase-sensitive optical low-coherence interferometry. The differential modal group delay and absolute chromatic dispersion values of each mode are retrieved from a single measurement without spatial mode transformers.

A Few Mode Fiber Temperature Sensor Filled With PDMS Based on Vernier Effect
IEEE Photonics Journal, 2021 A few mode fiber temperature sensor filled with PDMS based on vernier effect is proposed. It uses single mode fiber (SMF), few mode fiber (FMF), and polydimethylsiloxane (PDMS) to form the SMF-air microcavity-FMF-PDMS-FMF structure.

Intrinsic loss of few-mode fibers
Optics Express, 2018 We summarize theoretical formulae for determining the intrinsic loss of few-mode fibers and compare intrinsic losses among step-index and parabolic graded-index few-mode fibers (FMF) with different dopants, and with single-mode fibers (SMF). The low-loss characteristics of pure-silica-core FMFs, in comparison with SMFs, give rise to additional ...

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 ...

Nonlinear Pulse Distortion in Few-Mode Fiber [PDF]
European Conference and Exhibition on Optical Communication, 2012 Nonlinear pulse propagation in a few mode fiber is experimentally investigated, by measuring temporal and phase responses of the output pulses by use of a frequency discriminator technique, showing that self-phase modulation, dispersion and linear mode-coupling are the dominant effects.
