The design of an all-optical sequential circuit is one of the significant features of high-speed and fast-switching communication systems. Combinational and sequential logic circuits are both included in a real-world digital system. Thus, we cannot undervalue the significance of sequential logic circuits. Implementation of all-optical sequential circuits includes some great returns e.g. compact design, signal security, low electromagnetic interference, and larger bandwidth, etc. Here this paper displays the efficient application of micro-ring resonators to implement shift registers in the optical domain. The projected design is based on the Delay flip-flop which works on the principle of MRR switching activity. The necessary MATLAB simulated output of the suggested design is included in the study.
