The utility model provides an all-optical NAND gate, which comprises a first optical NOT gate, a second optical NOT gate and an optical OR gate, and is characterized in that the first optical NOT gate and the second optical NOT gate are respectively composed of an input end and an output end; the light OR gate consists of two input ends and one output end; the output end of the first optical NOT gate is connected with one input end of the optical OR gate; and the output end of the second optical NOT gate is connected with the other input end of the optical OR gate. Based on the design of a passive optical device, the device is simple in structure and convenient to integrate and expand; output signals are stable; based on logic calculation, the fault tolerance range is large, and strict frequency, phase and amplitude are not required; based on passive design, integration with other systems is easy. 本实用新型提供一种全光与非门，包括第一光非门，第二光非门以及光或门，其中：第一光非门和第二光非门均是由一个输入端和一个输出端组成；而光或门由两个输入端和一个输出端组成；所述第一光非门的输出端与光或门的一个输入端相连；所述第二光
