Abstract
An all-optical encryption system which can be used in fiber WDM system and directly encrypt multi-wave optical signals is proposed. This scheme achieves multi-wave signals encrypting by the technology of generating coherently multi-wave optical plain text, Key text and the technology of phase shift interference. The feasibility and validity of this encrypting scheme are verified by simulative experiment for multi-wave signals at 8x10Gbps with wavelength interval of 0.8nm, the simulative result shows that when the input Pi and Ki is Gauss pulse with duty cycle of 0.3, the bit error rate and Q factor of encryption output are 0 and 164 respectively. Theory analysis and simulative experiment shows the scheme is feasible and efficient.
