This paper presents the novel design of a digital photonic even parity bit generator based on a single photonic micro-ring resonator. This work provides the operational principle of the proposed circuit, with its inputs are the electrical signals being fed into the micro-ring resonator, and the optical signal output is taken from the ring drop port. Time varying simulation at the data rate of 10 Gbps have been tested, resulting in clear output timing diagram of the generated parity bit.
