This paper details the novel design, simulation and analysis of the digital photonic positive edge-triggered JK flip-flop using silicon micro-ring resonator as its core component. The designed silicon micro-ring resonator uses free carrier plasma dispersion electro-optic effect properties in its ring waveguide being structured as a PIN diode. There are altogether four silicon micro-ring resonators used in our proposed design, with each ring operates as specific logic mode operation. Time varying simulation have also been carried out, where two predetermined inputs for both J and K inputs, with a clock signal for CLK input, was injected into the circuit with the data rate of 1 Gbps. Its output is observed via multi-channel oscilloscope, where results are obtained with the simulation data sampling rate of 1.6 THz.
