Nonlinear Pulse Distortion in Few-Mode Fiber [PDF]

open access: yesEuropean Conference and Exhibition on Optical Communication, 2012
Nonlinear pulse propagation in a few mode fiber is experimentally investigated, by measuring temporal and phase responses of the output pulses by use of a frequency discriminator technique, showing that self-phase modulation, dispersion and linear mode-coupling are the dominant effects.

Few-Mode Fiber True Time Delay Lines [PDF]

open access: yes2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
Space-division multiplexing optical fibers can provide not only parallel channel transmission but also parallel distributed signal processing, being this a feature particularly attractive in Microwave Photonics applications. We present here few-mode fiber links with tailored modal propagation and dispersion properties that operate as sampled true time ...

Few-Mode Fibers With Uniform Differential Mode Group Delay for Microwave Photonic Signal Processing

open access: yesIEEE Access, 2020
We present a novel design of few-mode fiber (FMF) with a uniform differential mode group delay (U-DMGD) among propagating modes and apply the FMF to a single-fiber delay line module for implementing microwave photonic finite impulse response (FIR ...

Demonstration of Mode-Evolutional Multiplexer for Few-Mode Fibers Using Stacked Polymer Waveguide

open access: yesIEEE Photonics Journal, 2015
Mode-evolutional multi/demultiplexer for few-mode fibers was demonstrated using stacked polymer waveguides. Owing to the stacked structure, TE00, TE10, and TE01 modes, which correspond to LP01, LPeven11 , and LPodd 11 modes, respectively, were ...

Mode division multiplexing using an orbital angular momentum mode sorter and MIMO-DSP over a graded-index few-mode optical fibre [PDF]

open access: yes, 2015
Mode division multiplexing (MDM)– using a multimode optical fiber’s N spatial modes as data channels to transmit N independent data streams – has received interest as it can potentially increase optical fiber data transmission capacity N-times with ...

Singularities splitting phenomenon for the superposition of hybrid orders structured lights and the corresponding interference discrimination method

open access: yesNanophotonics, 2022
It is the basic characteristic of pure vortex light that there is a phase singularity at the origin. Such a singularity may be multiple degenerate, which determines the order of vortex light. Singularities splitting phenomenon means that singularities no
