Abstract
In this paper, a simple but novel scheme for all optical clocked D flip flop based on single micro-ring resonator with a feedback loop is proposed and prescribed. The GaAs-AlGaAs based micro-ring resonator is modulated through optical pump beam. The proposed clocked D flip flop presents two stable states determined by the phase shift in the ring and will allow synchronization of different optical devices by clock pulse (optical control pump beam). Theoretical model of clocked D flip flop has been developed using single micro-ring resonator and numerical simulation results confirming described methods are given in this paper. The design will be helpful in designing all optical integrated circuit.
