“…Now instead of formula (13), the amplitude a is given by a = 4(ω 2 − 1) + k 2 , and it is directly related to soliton speed c. We observe that at the instant a soliton is emitted from the localized wave, the wave envelope will increase its amplitude a a little, and it then starts propagating at a constant speed c. This is consistent with the theoretical prediction.…”

“…With a fairly good understanding of the soliton properties in regard to their existence, propagation, and interactions [1], creation of solitons has become a central topic in soliton physics, not only fundamental to understanding occurring solitonic phenomena in nature [2][3][4] and physical systems [5][6][7][8][9][10][11][12], but also very relevant to engineering applications of solitons [13][14][15]. Although solitons in integrable systems can in principle be evolved from properly given initial disturbances [16], it seems rather problematic to precisely control and realize the initial waveforms that would definitely evolve into what we desire.…”

We propose a mechanism for soliton creation from resonantly excited localized waves via supratransmission in band gaps of nonlinear lattices. A nonlinear localized wave, which is formed by and vibrates around an impurity with an intrinsic frequency, is found to undergo a local resonance when subject to an external forcing. Under the resonance, an instability develops that leads to the efficient emission of solitons at a much lower rate than that in uniform lattices with no impurity.

We propose and numerically study a simple scheme to obtain large pulse-width reduction of optical pulses generated by semiconductor lasers. The scheme consists of modulating two single-mode semiconductor lasers coupled through a normal dispersion fiber. The optimal pulse compression is obtained for a particular range of phase delay between the two modulated electrical injection currents. In addition, the optical pulses so obtained have a larger output power and are very close to transform-limited as required for soliton communication systems.

Applications of Nonlinear Fiber Optics

Soon after the nonlinear effects in optical fibers were observed experimentally, it was realized that they would limit the performance of fiber-optic communication systems [1]. However, nonlinear effects were found to be mostly irrelevant for system design in the 1980s because both the bit rate and link lengths were limited by fiber losses and group-velocity dispersion (GVD). The situation changed dramatically during the 1990s with the advent of optical amplification, dispersion management, and wavelength-division multiplexing (WDM). These advances increased link lengths to beyond 1000 km and single-channel bit rates to beyond 10 Gb/s. As a result, the nonlinear effects in optical fibers became of paramount concern for optimizing a lightwave system [2]- [5]. This chapter focuses on how the nonlinear effects influence the design of WDM lightwave systems. The loss-and dispersion-management techniques are discussed first in Section 7.1 as an introduction to system-related issues. Section 7.2 is then devoted to the impact of five major nonlinear effects stimulated Brillouin and Raman scattering (SBS and SRS), self-and cross-phase modulation (SPM and XPM), and four-wave mixing (FWM). Section 7.3 focuses on optical solitons that employ SPM to advantage and can be used for designing WDM systems. Section 7.4 describes intrachannel nonlinear effects that become important for high-speed channels in pseudo-linear lightwave systems.
