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.

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 ...
