Measurement of differential mode group delay in few-mode fibers based on Fresnel reflection peaks
Applied Optics, 2023Mode-division multiplexing communication based on few-mode fibers (FMFs) is the most competitive scheme to address the bandwidth exhaustion in single-mode fibers. The differential mode group delay (DMGD) among different modes in FMFs is an important aspect in characterizing FMFs, and the convenient, fast, and accurate measurement of DMGD in different ...

Simple and precise characterization of differential modal group delay arising in few-mode fiber
Optics Letters, 2021In this Letter, we propose a simple and high-precision differential modal group delay (DMGD) characterization method for few-mode fibers (FMF) by using the frequency-modulated continuous wave. Since the detected signals are located at the low-frequency range, our DMGD characterization method waives the use of expensive equipment, such as vector network

Low-Differential-Mode-Group-Delay 9-LP-Mode Fiber
Journal of Lightwave Technology, 2015We report the optimization of a few-mode fiber, adapted to multiple-input multiple-output mode division multiplexing, that supports 9 LP modes (15 spatial modes). The fiber is fabricated using standard multimode processes, which allows for tight process tolerances, yielding low differential mode group delays (2) and low bend losses.

Demonstration of Mode Scramblers Supporting 6 Spatial Modes to Reduce Differential Group Delays
2017 European Conference on Optical Communication (ECOC), 2017We demonstrate a mode scrambler for mixing 6 spatial modes. We present the characterization results of mode-dependent loss and modal transfer matrix using a swept-wavelength interferometer and verify group-delay spread reduction through principal mode analysis.

Optical Review, 2021
A reconfigurable and application-specific tunable microwave photonic filter having finite impulse response is proposed. The filter exploits the differential mode group delays of linearly polarized modes in a multi-mode fiber to achieve single and multiple high-frequency passband response.

We study the frequency autocorrelation of the differential group delay (DGD) in fibers with polarization mode dispersion (PMD). We show that the correlation bandwidth of the DGD is comparable with that of the orientation of the PMD vector. Furthermore, we show that all the most general statistical properties of polarization mode dispersion in long ...

Micro-bend-Resistant Low-Differential-Mode-Group-Delay Few-Mode Fibers
Journal of Lightwave Technology, 2017We report the design of micro-bend-resistant low-differential-mode-group-delay (low-DMGD) few-mode fibers that support up to six mode groups (12 LP modes, 21 spatial modes) and that are adapted to multiple-input multiple-output mode-division-multiplexed transmissions. Compared to previous designs, the micro-bending sensitivity is reduced by more than a
