Pm. Ramos et Cr. Paiva, INFLUENCE OF CROSS-PHASE MODULATION ON SELF-ROUTING PULSE SWITCHING IN NONLINEAR-OPTICAL FIBERS, Microwave and optical technology letters, 15(2), 1997, pp. 91-95
Based on the Lagrangian formulation, we present a new variational appr
oach to study the influence of cross-phase modulation on solitonlike p
ulse switching in twin-core fiber couplers and birefringent fibers. Fo
r self-routing pulse switching we found an excellent agreement between
our finite-dimensional Hamiltonian system and the split-step Fourier
method. (C) 1997 John Wiley & Sons, Inc.
