An optical synchronous up counter based on electro-optic effect of lithium niobate based Mach–Zehnder interferometers

Abstract

Sequential circuits have the ability to store, retain and then retrieve information when needed at a later time. They act as storage elements and have memory. However, due to ever increasing demand of data rate, already existing electronic signal processing devices have become obsolete due to their large latency. To overcome the existing bottleneck, a 4-bit synchronous up counter using electro-optic effect of Mach-Zehnder interferometer has been proposed. The study is carried out by simulating the proposed device with beam propagation method.

“…Likewise, optical signal processing is quite instrumental in the field of telecommunication networks due to its large bandwidth [1], low electromagnetic interference (EMI), and high speed [2,3]. Hence, in order to attain the signal transmission and processing, optical circuits are considered very bright prospects which are capable of providing promising solutions.…”
