An ultrafast encryption decryption scheme is proposed at 160 Gb/s for secure transmission over optical networks. Proposed Encryption decryption circuits have been designed using semiconductor optical amplifier based XOR logic with delay interferometer. Delay interferometer is used to mitigate effect of slow carrier recovery in semiconductor optical amplifier which act as a bottleneck specially for high data rate signal transmission. The system performance is evaluated and investigated in terms of extinction ratio and quality factor. The results demonstrate that proposed scheme is feasible and offers high level of security at ultrafast data rate.
