An optical soliton pulse may be used as a control signal in nonlinear optic
al loop mirror demultiplexers in order to reduce timing-jitter noise and cr
osstalk. A mathematical model for calculating the width of the soliton swit
ching window and optimizing critical parameters such as walk-off time and p
ulse width has been presented, and its accuracy is verified by solving the
nonlinear Schrodinger equation. (C) 1999 John Wiley & Sons, Inc.
