Nonlinear interaction in differential mode delay managed mode-division multiplexed transmission systems

open access: yesOptics Express, 2015
We analyze the impact of Differential Mode Delay (DMD) Management on the nonlinear impairments in mode-division multiplexed transmission systems. It is found out that DMD Management can lead to a degraded performance, due to enhanced intermodal nonlinear interaction. This can be attributed to an increased correlation of co-propagating channels, similar

Temporal Cavity Soliton Interaction in Passively Mode-Locked Semiconductor Lasers

open access: yesOptics, 2023
Weak interactions of temporal cavity solitons resulting from gain saturation and recovery in a delay differential model of a long cavity semiconductor laser were studied numerically and analytically using an asymptotic approach.

Simultaneous Measurement of MDL and DMGD in FMFs by Analyzing the Rayleigh Backscattering Amplitudes

open access: yesIEEE Photonics Journal, 2019
In this paper, we propose and experimentally demonstrate a novel method for simultaneously measuring mode-dependent loss (MDL) and differential modal group delay (DMGD) in few mode fibers (FMFs).

Modeling pulsativity in the hypothalamic–pituitary–adrenal hormonal axis

open access: yesScientific Reports, 2022
A new mathematical model for biological rhythms in the hypothalamic–pituitary–adrenal (HPA) axis is proposed. This model takes the form of a system of impulsive time-delay differential equations which include pulsatile release of adrenocorticotropin ...

A delay differential equation NOLM--NALM mode-locked laser model

open access: yes, 2021
Delay differential equation model of a NOLM-NALM mode-locked laser is developed that takes into account finite relaxation rate of the gain medium and asymmetric beam splitting at the entrance of the nonlinear mirror loop. Asymptotic linear stability analysis of the continuous wave solutions performed in the limit of large delay indicates that in a ...

Delay-dependent exponential stability of neutral stochastic delay systems [PDF]

open access: yes, 2009
This paper studies stability of neutral stochastic delay systems by linear matrix inequality (LMI) approach. Delay dependent criterion for exponential stability is presented and numerical examples are conducted to verify the effectiveness of the proposed

Enhancing Common-Mode Loop Stability of Three-Phase Four-Bridge Grid-Connected Inverters via Control Delay

open access: yesEnergies
As the three-phase four-bridge inverter (3P4B) can effectively compensate for the unbalanced three-phase loads in the grid, it is an important converter option for distributed generation grid connection.

Multiband Real-Time Coherent Optical OFDM Reception up to 110 Gb/s with 600-km Transmission

open access: yesIEEE Photonics Journal, 2010
We demonstrate field-programmable gate array (FPGA)-based multiband orthogonal frequency-division multiplexing (OFDM) signal reception after 600-km standard single-mode fiber (SSMF) transmission and 400-ps differential-group delay (DGD) at 110-Gb/s.
