From the last few decades the optical communication has been established as much easier process thanelectrical communication. Many optical proposed circuits have already been suggested in many fields insupport of this. The optical communication circuits demand frequency dividers capable of operating wellabove 10 GHz. Here, an all-optical frequency divider using terahertz optical asymmetric demultiplexer (TOAD)based D-flip-flop is proposed in the optical domain in a configuration exactly like the standard electronicsetup. It presents a high-speed flip-flop-based frequency divider incorporating a new high-speed latchtopology with satisfactory performance. The proposed all-optical frequency division scheme has beentheoretically demonstrated in this paper. In this scheme the input and output binary digits are expressed asthe presence (1) and the absence (0) of the light pulses. The performance of this proposed optical realization isevaluated by numerical simulation that confirms its feasibility in terms of the choice of the criticalparameters.
