Abstract
We demonstrate a 5.8pJ switching energy all-optical NOR-gate with a fanout of six that is based on timing shifts from soliton dragging [1] in a fiber. This three-terminal, cascadable gate satifies all requirements for a clocked digital optical processor. Furthermore, we describe here an equivalent circuit for soliton dragging in terms of a generalized exclusive-or (GEO) module. By changing the interconnections between two GEO-modules, we can implement NOR and AND-gates or broadcast and routing switches.
