Low-energy ultrafast fiber soliton logic gates
Abstract:
We have reduced the switching energy for an all-optical soliton dragging NOR gate to 5.8 pJ by using a two-fiber configuration and optimizing the fiber and laser parameters. The cascadable NOR gate has a fanout of six, restores both the logic level and timing, and can operate at bit rates of up to 0.2 THz. In addition, we show that soliton dragging can be represented as a generalized exclusive-or module with high functionality. Two such modules can be interconnected as NOR and AND gates or broadcast and routing switches.
