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 ...

A digital delay locked loop with a monotonic delay line

open access: yesElectronics Letters, 2023
This paper proposes a digital delay locked loop (DLL) with a monotonic delay line (DL). This DLL adopts the calibration mode to reduce the non‐monotonic effects for the coarse‐tuning delay line (CTDL) and the fine‐tuning delay line (FTDL).
