Optical nonlinearities give rise to many ubiquitous effects in optical fibers. These effects are
interesting in themselves and can be detrimental in optical communications, but they also …

Several approximate non-linear fiber propagation models have been proposed over the
years. Recent re-consideration and extension of earlier modeling efforts has led to the …

In this paper, we develop a general first-order perturbation theory of the propagation of a
signal in an optical fiber in the presence of amplification and Kerr nonlinearity, valid for …

Fiber-optic communication systems have revolutionized our telecommunication
infrastructures–currently, almost all telephone land-line, cellular, and internet …

The performance of high-speed digital fiber-optic transmission using subcarrier multiplexing
(SCM) is investigated both analytically and numerically. In order to reduce the impact of fiber …

Transmission performance of ultra-dense 2.5-and 10-Gb/s nonreturn-to-zero intensity-
modulated direct-detection wavelength-division-multiplexing systems in various single …

A main drawback of Coherent Optical Orthogonal Frequency Division Multiplexing (CO-
OFDM) system is its sensitivity to fiber nonlinearity. Nonlinear electrical equalizer based on …

New analytical tools to calculate the variance due to cross-phase modulation (XPM) and four-
wave mixing (FWM) induced intensity distortion are derived based on the Volterra series …

This chapter aims to provide a comprehensive picture of the impact of fiber nonlinear effects
on modern coherent wavelength division multiplexing (WDM) systems' performance. First …

Gordon and Mollenauer, in their famous paper published in 1990, laid out how the interplay
between the nonlinear Kerr effect in optical fibers and the amplified spontaneous-emission …
