Micro-ring resonator (MRR)-based switching is one of the promising technologies in modern optical signal processing and optical computing. In this paper, we present a scheme of all-optical 2-bit ripple down counter, using the MRR-based all-optical switching activity. The proposed mechanism shows the generation of all-optical two bits ripple down sequences without any involvement of electrical pumping. The optical pumping shows one of the innovative ways to overcome the complexity associated with electrical pumping. The paper includes the detailed mathematical analysis of all-optical switches in the form of a micro-ring resonator structure. We proposed four cascaded micro-ring resonator structures representing all-optical ripple down counters, and numerical simulation is presented with some additional analysis. The proposed design is simple and may be helpful for all-optical signal processing and logical computation.Author names: Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).
