Fast mode decomposition in few-mode fibers [PDF]
Nature Communications, 2020 Characterizing the modes at the output of a multimode fiber is time consuming due to computational cost. Here the authors present an algorithm for few-mode-fiber mode decomposition with a fast processing time and using only intensity measurements.

Forward Brillouin scattering in few-mode fibers [PDF]
Light: Science & ApplicationsForward Brillouin scattering is an opto-mechanical effect in which two co-propagating optical fields couple with an acoustic mode in a common medium. The effect has been studied in standard optical fibers since 1985, however nearly all studies have been ...

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 ...

Towards universal multi-dimensional parallelization communications by direct diverse fiber/3D/2D chip hybrid integration [PDF]
Nature CommunicationsSpace-division multiplexing (SDM) is a promising technology for significantly increasing the capacity of a single fiber or waveguide. Various SDM fibers, including few-mode fibers (FMFs), multi-core fibers (MCFs), and orbital angular momentum fibers ...

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.

Sparse intensity sampling for ultrafast full-field reconstruction in low-dimensional photonic systems [PDF]
Communications PhysicsPhase-sensitive measurements usually utilize interferometric techniques to retrieve the optical phase. However, when the feature space of an electromagnetic field is inherently low dimensional, most field parameters can be extracted from intensity ...

Interconnection of Few-Mode Fibers and Photonic Integrated Circuits Using Mode-Field Adapters
Photonics, 2022 We propose a detailed method for the interconnection between optical fibers and waveguides of photonic integrated circuits. Appropriate modal transmission is accomplished by matching the mode field diameters from both waveguide structures. Links from one
