Abstract
The present invention discloses a photonic crystal (PhC) all-optical multistep-delay AND-transformation logic gate, which comprises a PhC-structure unit, an optical-switch unit (OSU), a wave-absorbing load, a NOT-logic gate, a D-type flip-flop (DFF) and a memory or delayer; an input port of a memory is connected with a first logic-signal X, and an output port of the memory is connected with the delay-signal-input port of the OSU; a second logic-signal Xis connected with the logic-signal-input port of the OSU; two intermediate-signal-output ports of the OSU are respectively the intermediate-signal-input port of the PhC-structure unit and the wave-absorbing load; a clock-signal CP is connected with the input port of a three-branch waveguide; the signal-output port of the PhC-structure unit is connected with the D-signal-input port of the DFF unit. The structure of the present invention is compact in structure and ease of integration with other optical-logic elements.
