This paper presents novel optical encryption and decryption systems using a semiconductor optical amplifier at 40 Gb/s. Proposed scheme exploits cross-phase modulation phenomenon in SOA. Our design is mainly based on SOA Mach-Zehnder interferometer structure, optical couplers, CW light, and EDFA. We demonstrate that our implementation is more feasible than conventional SOA-MZI encryption system, where only single optical pulse source is used. Experimental evaluation using eye diagrams shows robustness of our proposed encryption decryption system against eavesdropping.
