Long distance transmission in few-mode fibers
Optics Express, 2010 Using multimode fibers for long-haul transmission is proposed and demonstrated experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good compromise since they are sufficiently resistant to mode coupling compared to standard multimode fibers but they still can have large core diameters compared to single-mode fibers.

Graphene mode locked, wavelength-tunable, dissipative soliton fiber laser
, 2010 Atomic layer graphene possesses wavelength-insensitive ultrafast saturable absorption, which can be exploited as a full-band mode locker. Taking advantage of the wide band saturable absorption of the graphene, we demonstrate experimentally that wide ...

Enhancement of modal stability through reduced mode coupling in a few-mode fiber for mode division multiplexing [PDF]
, 2018 We demonstrate a novel approach to enhance the modal stability between the modes of a few-mode fiber (FMF) by increasing the effective index differences between these modes.

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

Sub-sampled modal decomposition in few-mode fibers
Optics Express, 2021 Retrieving modal contents from a multimode beam profile can provide the most detailed information of a beam. Numerical modal decomposition is a method of retrieving modal contents, and it has gained significant attention owing to its simplicity. It only requires a measured beam profile and an algorithm.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Few-Mode Fibers: Characterizations and Applications
2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023 We report design guidelines and modal loss characterizations (light scattering and extra-loss phenomena) of few-mode fibers that allow optimizing their crosstalk, differential mode group delay and differential mode attenuation for practical applications.
