Implementation of full-adder and full-subtractor based on electro-optic effect in Mach-Zehnder interferometers

The optical switching phenomena has been studied and its efficient application to construct the full-adder/subtractor (A/S) has been projected. The paper constitutes the mathematical description of proposed device and thereafter compilation using MATLAB. The analysis of various factors such as crosstalk, extinction ratio, power imbalance and transition loss has been presented. The desirable device parameter has been examined in order to obtain the optimum best influencing parameter. The work is carried out by simulating the proposed device with Beam propagation method and using the observed results to study the characteristics of influencing parameters in consideration with the device parameters.
