| Abstract: | With the FWM effect in nonlinear fibers,a novel high speed all-optical AND gate scheme is proposed.On the basis of transmission equation of pulse in nonlinear fiber and FWM principle,an all-optical AND gate theoretical model is developed.A 40Gbit/s AND gate is realized by numerical simulation,and the affection to the AND output introduced by the walk-off effect owing to group velocity mismatch is also studied. |
