STABLE SOLITON PAIRS IN OPTICAL-TRANSMISSION LINES AND FIBER LASERS

Optical-fiber transmission of pulses can be modeled with the complex G inzburg-Landau equation. We find novel stable soliton pairs and trains , which are relevant in this case, and analyze them. We suggest that t he distance between the pulses and the phase difference between them i s defined by energy and momentum balance equations, rather than by equ ations of standard perturbation theory. We present a two-dimensional p hase plane (interaction plane) for analyzing the stability properties and general dynamics of two-soliton solutions of the Complex Ginzburg- Landau equation.
