Abstract: A non-linear material (NLM) based all-optical switching mechanism is exploiting here to realize the all-optical T flip-flop without preset (PR) and clear (CLR). The all-optical switch by a composite slab of linear medium (LM) and non-linear medium is the building block of our proposed flip-flop circuit. As the flip-flops are sequential logic circuits, the present states of outputs are dependent not only on the present inputs but also on the past outputs. In our present scheme the outputs are fed back to the former stages as well as the input stages. The output of the flip-flop and its complement are obtained simultaneously in our scheme.
