Phase-Sensitive Mode Conversion and Equalization in a Few Mode Fiber Through Parametric Interactions
IEEE Photonics Journal, 2017 The parametric interaction in few mode fibers is theoretically and numerically studied in the particular case in which the signal and the idler waves are frequency degenerate but mode nondegenerate.

Design of Highly Elliptical Core Ten-Mode Fiber for Space Division Multiplexing With 2 × 2 MIMO
IEEE Photonics Journal, 2019 In this paper, we propose a weakly coupled few-mode fiber requiring only 2 × 2 multi-in multi-out equalizer blocks, which makes it compatible with standard coherent receivers with polarization diversity.

Observation of multimode solitons in few-mode fiber
Optics Letters, 2016 We experimentally isolate and directly observe multimode solitons in few-mode graded-index fiber. By varying the input energy and modal composition of the launched pulse, we observe a continuous variation of multimode solitons with different spatiotemporal properties. They exhibit an energy-volume relation that is distinct from those of single-mode and

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.
