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 ...

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 ...

Wideband and Low-Loss Mode Scrambler for Few-Mode Fibers Based on Distributed Multiple Point-Loads

open access: yesIEEE Photonics Journal, 2021
We propose a new type of all-fiber mode scrambler for mode division multiplexed data transmission based on few mode fibers. By randomly placing multiple point-loads along the fiber length, low loss and wideband mode coupling is obtained amongst all the ...

Design and Characterization of Nanopore- Assisted Weakly-Coupled Few-Mode Fiber for Simpler MIMO Space Division Multiplexing

open access: yesIEEE Access, 2020
We report on a novel weakly-coupled 6-LP-mode fiber that features a nanopore-assisted step-index core with double-cladding profile. The purpose of this fiber design is to alleviate modes coupling and bend sensitivity, thus simplifies the multiple-input ...

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

Modeling large air fraction holey optical fibers [PDF]

open access: yes, 2000
We develop a modal decomposition approach to solve the full vector wave equation for holey optical fibers (HF). This model can be used to explore the modal properties of a wide range of HFs, including those with large air holes. The optical properties of
