In this paper, we propose and investigate some designs of basic plasmonic logic gates in two dimensional plasmonic waveguides with nanotube metal-insulator-metal waveguides using the numerical method of eigenmode expansion. These gates, including XOR, OR, NOT, and Feynman gate can be realized by changing geometrical parameters properly. Also, by cascading and combining these basic logic gates, any complex logic function can also be obtained providing the highly integrated optical logic circuits. The proposed logic gates have the broadband up to 300 nm and only spend the compact size as much as 2 µm×1.2 µm. Thus, the devices can be applied widely and significantly in optical computing and processing devices.
