摘要：
In this work, an optimized design of all-optical NAND gate using plasmonic-based Mach-Zehnder Interferometer (P-MZI) is proposed using the metal-insulator-metal waveguide. It is an essential element for ultra-fast logic designing in integrated circuits at nanoscale. The proposed structure is designed with the minimum number of P-MZIs to operate in 1550nm wavelength. The chip area of the proposed devices is 40 x 7.5 mu m. The performance is analyzed and ER and IL obtained as 10.25 dB and 0.756dB respectively which are promising data for the device. The analysis is done via MATLAB software and finite-difference time domain (FDTD) method and the proposed device is studied.
