All-optical clocked D flip-flop using modified Add/Drop Resonance Ring

This paper, we propose scheme for all-optical clocked D flip-flop based on Modified Add/Drop Resonance Ring (MARR). The proposed all-clocked D flip-flop presents two stable states determined by the phase shift in the resonance ring and will allow synchronization of different optical devices by clocked pulse. Theoretical model of clocked D flip-flop has been developed using MARR and simulation results confirming described methods are given in this paper.
