Abstract(English):

The invention discloses a silicon-based electro-optic logic AND/NAND gate. The silicon-based electro-optic logic AND/NAND gate comprises a first 2*2MZI type electro-optic switch, a second 2*2MZI type electro-optic switch and a 2*1MMI coupler. Each of the first and second 2*2MZI type electro-optic switches comprises a first input end, a second input end, a first output end and a second output end, and the 2*1MMI coupler comprises a first input end, a second input and an output end. The first output end of the first 2*2MZI type electro-optic switch is connected with the first input end of the second 2*2MZI type electro-optic switch, and the first output end of the second 2*2MZI type electro-optic switch is an AND logic output end. The second output end of the second 2*2MZI type electro-optic switch is connected with the first input end of the 2*1MMI coupler, the second output end of the first 2*2MZI type electro-optic switch is connected with the second input end of the 2*1MMI coupler, and the output end of the 2*1MMI coupler is an NAND logic output end. The silicon-based electro-optic logic AND/NAND gate has the advantages of high extinction ratio, high speed, large broadband and large fabrication tolerance.
