Spatiotemporal Soliton Attractor in Multimode Graded-index Fibers [PDF]

2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021
There is recently a considerable interest in nonlinear optical effects in multimode fibers (MMFs). Here we present the experimental evidence, supported by numerical simulations, that an initially excited multimode femtosecond soliton initially composed by few low-order transverse modes of a graded-index (GRIN) MMF irreversibly decays into a singlemode ...

High Power All-Fiber Supercontinuum System Based on Graded-Index Multimode Fibers

Applied Sciences, 2022
An all-fiber supercontinuum source based on graded-index multimode fibers is reported. The supercontinuum source is based on a homemade mode-locked oscillator and a three-stage picosecond amplifier, which obtained the supercontinuum by a graded-index ...

High Power Supercontinuum Generation in Graded-Index Multimode Fibers [PDF]

2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019
Over the years, supercontinuum generation in fibers are studied extensively. Photonic crystal fiber technology detailed these studies by allowing the change of dispersion parameter. Nowadays, multimode fibers attracted huge attention by enabling spatiotemporal nonlinearities and multimodal interactions.

Graded-index breathing solitons from Airy pulses in multimode fibers [PDF]

Optics Express, 2019
Breathing solitons, as localized wave packets with a periodic evolution in amplitude and duration, are able to model extreme wave events in complex nonlinear dispersive systems. We have numerically studied the formation and manipulation of graded-index breathing solitons embedded in nonlinear multimode fibers based on a single nonlinear Schrödinger ...

Investigation of bandwidth in multimode graded-index plastic optical fibers

Optics Express, 2021
A new method is proposed for investigating the bandwidth in multimode graded-index plastic optical fibers (GI POFs). By numerically solving the time-dependent power flow equation, bandwidth is reported for a varied launch conditions (radial offsets) of multimode GI POF.

Mode-multiplexed transmission over conventional graded-index multimode fibers [PDF]

Optics Express, 2015
We present experimental results for combined mode-multiplexed and wavelength multiplexed transmission over conventional graded-index multimode fibers. We use mode-selective photonic lanterns as mode couplers to precisely excite a subset of the modes of the multimode fiber and additionally to compensate for the differential group delay between the ...

Spatio-Temporal Behaviour of Femtosecond Solitons in Graded-Index Multimode Fibers [PDF]

2021 International Conference on Electrical, Computer, Communications and Mechatronics Engineering (ICECCME), 2021
We present a new class of spatiotemporal walk-off solitons in graded-index multimode optical fibers, characterized by unique properties. Their energies and pulsewidths depend only on chromatic and modal dispersion of the fiber, and on the input laser beam coupling conditions.
