The performance of resonant channel-dropping filters in WDM applicatio
ns is computed. 31 and 50 filters are cascaded along a single bus with
crosstalks of -27 and -14 dB, respectively. The temporal response of
the filter from a secant-hyperbolic pulse stream at 400 Mb/s and 1 Gb/
s is presented. The simulation shows the promise of resonant-filter ca
scades.
