Optical encryption and decryption system is successfully demonstrated by using cross-gain modulation (XGM) in semiconductor optical amplifiers (SOAs). Transmission speed of 40 Gbps is successfully achieved. Our proposed scheme exploits cross phase modulation phenomenon in SOA. Our design is mainly based on SOAMach-Zehender interferometer structure, optical couplers, CW light & EDFA. Experimental evaluation using eye diagrams shows robustness of our proposed encryption decryption systems against eavesdropping.
