Research on fiber nonlinear coefficient

2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017
We make some measurement research based on CW SPM method, and obtain the non-linear coefficient for the novel ultra low loss& large effective area single mode fiber. And we also discussed the measure uncertainty and non-linear coefficient influence factor.

Photonic crystal fiber supporting 394 orbital angular momentum modes with flat dispersion, low nonlinear coefficient, and high mode quality

Optical Engineering: The Journal of SPIE, 2022
. A photonic crystal fiber (PCF) with an SSK2 dense crown glass ring is designed and analyzed. After optimization of the radius of the central air hole and thickness of the annular region, 394 orbital angular momentum (OAM) modes in the range of 1.48 to ...

Solving coefficient inverse problems for nonlinear singularly perturbed equations of the reaction-diffusion-advection type with data on the position of a reaction front

Communications in nonlinear science & numerical simulation, 2021
An approach to solving coefficient inverse problems for nonlinear reaction-diffusion-advection equations is proposed. As an example, we consider an inverse problem of restoring a coefficient in a nonlinear Burgers-type equation.

Modulation instability in waveguides with an arbitrary frequency-dependent nonlinear coefficient.

Optics Letters, 2020
In this Letter, we present, for the first time, to the best of our knowledge, the modulation instability (MI) gain spectrum of waveguides with an arbitrary frequency-dependent nonlinear coefficient ensuring strict energy and photon-number conservation of

Ultrasound coefficient of nonlinearity imaging

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015
Imaging the acoustical coefficient of nonlinearity, β, is of interest in several healthcare interventional applications. It is an important feature that can be used for discriminating tissues. In this paper, we propose a nonlinearity characterization method with the goal of locally estimating the coefficient of nonlinearity.
