摘要：

Set-Reset (SR) latch or flip-flop is bistabile circuit. The circuit maintains a binary state indefinitely until directed by an input signal (clock signal) to switch state. Sequential logic circuits for specific application can be implemented by using SR flip-flop and external gates. In this article, SR latch and SR flip-flop is proposed using electro-optic effect inside lithium-niobate-based Mach-Zehnder interferometers (MZIs). The MZI structures have the powerful capability of switching an optical input signal to a desired output port. The article constitutes a mathematical description of the proposed device and thereafter simulation using MATLAB. The study is verified using beam propagation method (BPM). © 2019 Walter de Gruyter GmbH.
