摘要：

By exploiting the phenomena of optical switching, different logical and arithmetic operations can be performed. This paper presents a novel optimized design structures to perform addition and subtraction of two binary digits using electro-optic effect based Mach-Zehnder interferometer operating at 1460 nm in the S band. The proposed structures are numerically simulated and designed using beam propagation method and MATLAB software. The different performance parameters like extinction ratio, contrast ratio, insertion loss, amplitude modulation and relative eye opening have been evaluated and the optimized structure yields maximum ER of 33.22 dB and 28.76 dB for half adder and half subtractor respectively. Additionally, a comparison of the proposed structures is presented with the previously designed structures.
