Abstract

See full text

Combinatorial logic devices are presented in which data signals interact with an enable signal in the device to move the enable signal outside its prescribed time slot when one or both of the data signals are present. Data signals are discarded within the device to avoid propagation through subsequent logic device stages. Such logic devices are particularly well suited to all-optical realizations in which soliton pulse signals are used. These devices exhibit high gain, cascadability and potentially large fanout capability.
