Abstract
The present invention discloses a PhC all-optical self-AND-transformation logic gate, which comprises an optical-switch unit, a PhC-structure unit, a NOT-logic gate and a D-type flip-flop unit; said clock-signal CP is connected with an input port of the two-branch waveguide, said two output ports of the two-branch waveguide are respectively connected with the input port of said NOT-logic gate and a first clock-signal-input port of said PhC-structure unit; the output port of said NOT-logic gate is connected with the second clock-signal-input port of said D-type flip-flop unit; the signal-output port of the PhC structure is connected with the D-signal-input port of said D-type flip-flop unit; a logic-signal X is connected with the logic-signal-input port of said PhC-structure unit. The structure of the present invention is compact in structure and ease of integration with other optical-logic elements.
