Abstract :
Theoretical and experimental switching windows for all-optical demultiplexing from 160 to 10 Gb/s and 40 Gb/s, using a gain-transparent ultrafast nonlinear interferometer are presented. Based on these results we determined the maximum transmittance and the integrated contrast ratio, measures for switching losses and crosstalk from neighboring channels, respectively. Demultiplexing to 40 Gb/s (as compared to 10 Gb/s) leads to 6 dB lower maximum transmittance and 3 dB higher integrated contrast ratio (lower crosstalk).
