Plasmonic metal–insulator–metal (MIM) waveguides have the unique attribute of propagating surface plasmons beyond the diffraction limit. In this paper, basic designs for half-adder and half-subtractor circuits are proposed based on the nonlinear effect in Mach–Zehnder interferometers designed using plasmonic MIM waveguides. The proposed devices are studied in the third optical communications window with transverse magnetic polarization. The designs are verified by the finite-difference time-domain technique with the help of MATLAB simulations.
