We treat the creation of solitons in amplifying fibers. Strictly speaking, solitons are objects in an integrable setting while in real-world systems loss and gain break integrability. That case usually has been treated in the perturbation limit of lo

This is a review of fiber-optic soliton propagation and of methods to determine the soliton content in a pulse, group of pulses or a similar structure. Of central importance is the nonlinear Schrödinger equation, an integrable equation that possesse

We demonstrate a novel type of ultrashort optical soliton bound states with molecule-like properties. These two-color solitons exhibit a strong binding energy, dipole-like radiation, and show dynamics of controlled soliton evaporation. Furthermore, t

Recent developments in the technology of optical telecommunications are pushed forward by the rapidly growing demand for data-carrying capacity. Current approaches are discussed; most lines of investigation are limited to the linear (i.e. low power)

We demonstrate a peculiar mechanism for the formation of bound states of light pulses of substantiallydifferent optical frequencies, in which pulses are strongly bound across a vast frequency gap. This isenabled by a propagation constant with two sep

The impact of power loss on fiber-optic solitons and soliton compounds has regained interest recently, as coding schemes employing inverse scattering eigenvalues are being discussed. Loss lifts the integrability of the underlying nonlinear Schr\"odin

Propagation of solitons in fibers with gain or loss beyond the perturbative regime is considered. Analytical results, corroborated with soliton eigenvalues from numerical studies, predict generation and decay of solitons, and the energy budget.

We consider the evolution of fiber-optic solitons in the presence of loss. Localized power reduction can be cast into a well-known form for which changes of all parameters are known explicitly. We proceed to a sequence of such perturbations with the

Realistically, any discussion of fiber-optic solitons must consider the impact of gain and loss. Even when both are balanced on average, pulse reshaping does occur, and radiation is generated (which drains energy from the soliton). Mathematically spe
