Nonlinear Coefficient Measurement in Highly Dispersive Fibers

Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF), 2018
We present a novel approach for measuring nonlinear coefficients in fibers with significant pulse broadening. We perform a proof-of-concept demonstration for 200-m-long polarization-maintaining and single-mode fibers pumped at 1060 nm with ps pulses.

A Nonlinear Random-Coefficients Model for Degradation Testing

Technometrics, 2004
As an alternative to traditional life testing, degradation tests can be effective in assessing product reliability when measurements of degradation leading to failure can be observed. This article presents a degradation model for highly reliable light displays, such as plasma display panels and vacuum fluorescent displays (VFDs).

Determination of nonlinear coefficient n2/Aeff using self-aligned interferometer and Faraday mirror

, 2000
A method for measuring the nonlinear coefficient n/sub 2//A/sub eff/ in telecom fibres at 1550 nm is presented. The method is based on determining the Kerr phase shift detected by a self-aligned interferometer incorporating a Faraday mirror.

Remarks on "On the coefficient of nonlinearity in nonlinear acoustics"

2015
Through an alternate analysis, the results of Hamilton and Blackstock [J. Acoust. Soc. Am. 83, 74-77 (1988)] are reviewed and a new interpretation is presented. In this view, the nonlinearity of the momentum equation is examined, and its effect on the coefficient of nonlinearity is revealed.

A family of nonlinear filters with data dependent coefficients

IEEE Transactions on Signal Processing, 1995
A new family of data dependent nonlinear filters (DDNL) is presented. Coefficients are computed locally and the absolute distance between signal samples is used to determine a rank order dependent weighting function. The new filters have very good performance regarding noise suppression and impulse rejection and at the same time provide better edge ...

Interpolation of the Coefficients in Nonlinear Elliptic Galerkin Procedures

SIAM Journal on Numerical Analysis, 1984
The use of interpolation for the evaluation of integrals in nonlinear Galerkin methods can lead to important savings in computational effort. \textit{I. Christie, D. F. Griffiths, A. R. Mitchell} and the first author [IMA J. Numer. Anal. 1, 253-266 (1981; Zbl 0469.65072)] have introduced the term product approximation to refer to finite-element ...

Nonlinear modeling of wavelet coefficients around edges

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
State of the art image coders make use of various methods to exploit intra and inter-band dependencies of wavelet coefficients in order to improve performance. While these efforts achieve considerable bitrate reduction for coding clusters of insignificant coefficients in smooth areas, most of the bitrate is spent on coding wavelet coefficients that are
