Implementation of 3-bit asynchronous binary up-down counter using Electro-Optic Effect based Mach-Zehnder Interferometers

In photonic communication systems, Electrooptic effect-based Mach-Zehnder Interferometer is a crucial component that significantly determines the achievable data transmission rate. Recent developments in manufacturing and processing methods have provided a renewed focus for research on optical switching. Optical logic gates, Flip-flops, latches, and other digital electronic systems are the essential components of next-generation high-speed communication networks for advancement in technology of computers, communication systems, combinational and sequential circuits and can be used as fundamental building blocks for large integrated circuits. The present work shows the development of a T flip flop and a 3-bit asynchronous binary up-down counter using a minimum number of MZI switches. This approach ensures low optical cost in the performance of all proposed devices. MATLAB software has been used for the realization of devices. The simulation result has been validated by the relevant devices standard results.
