Soliton propagation in optical devices with two-components fields: a comparative study

摘要

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. © 1995 Optical Society of America
