The problem of solitonlike pulse propagation in optical fiber devices with two-component fields is studied. Two
examples, viz., propagation of pulses in birefringent optical fibers and in nonlinear couplers, are considered.
It is shown that radiation processes play an essential role in the soliton dynamics in two-component field
fiber devices. Radiation influences the transformation of the main pulses in different ways in the two cases
considered. The influence of radiation is stronger when the soliton is closer to the point of bifurcation or the
separatrix and weaker when it is far from it.
1. INTRODUCTION
Pulse propagation in two-mode fiber devices can be
treated as a problem of the evolution of a dynamical
system with an infinite number of degrees of freedom.1
The two most frequently studied examples of this kind
