Pm. Ramos et Cr. Paiva, OPTIMIZATION AND CHARACTERIZATION OF PHASE-CONTROLLED ALL-OPTICAL SWITCHING WITH FIBER SOLITONS, IEEE journal of selected topics in quantum electronics, 3(5), 1997, pp. 1224-1231
Using a variational approach based on the Lagrangian formulation, cons
isting of an adiabatic perturbation of two coupled fiber solitonlike p
ulses, we present an optimization procedure for phase-controlled all-o
ptical switching. Large phase intervals for both the parallel-and cros
s-state of the nonlinear coupler are determined, By means of a unified
theoretical framework, which takes into account the effect of cross-p
hase modulation (XPM), both twin-core fiber couplers and birefringent
optical fibers are considered, The influence of several errors in the
weaker control pulse-such as time delay and pulsewidth fluctuations-on
the transmission characteristics of the nonlinear coupler is also inv
estigated.
