We analyze and numerically study the code-matching logic module that i
s the central element in a proposed soliton-based ring network system
running at peak rates of 100 Gb/s. The proposed network is packet-swit
ched, and fast logic is required to route each packet. That is the fun
ction of the code-matching logic module, and four soliton logic gates
that can perform fast logic are the key devices in its design. The beh
avior of the code-matching logic module is governed by a large set of
parameters, and we simulate it by varying many of these parameters. Th
e physical effects that occur in these de,ices and their significance
are analyzed. The results indicate that the logic module will work but
within a restricted parameter range.
