Abstract. Photonic firewalls that can directly conduct the data discrimination and intrusion detection at the optical layer are an important security technique for optical networks. In the photonic firewall, binary sequence matching module is the core part and is implemented by multiple all-optical logic gates such as all-optical AND gate, all-optical XOR gate, etc. However, the semiconductor optical amplifier (SOA)-based all-optical logic gates have the disadvantages of low operation rate which leads to low matching rate. We design a binary sequence matching module that is implemented by the cross-phase modulation effect (XPM) and the four-wave mixing effect (FWM) of the highly nonlinear fiber (HNLF). The nonlinear effect of HNLF has a very short response time, thus it can realize the logic operation at a very high optical signal rate. The developed binary sequence matching module is verified through VPI Transmission Maker 8.5. The simulation results show that it can achieve the matching of 8-bit data in 64-bit binary data at 160-Gbps signal rate.

高非线性光纤中基于交叉相位调制和四波混频的二进制序列匹配系统

摘要。可以直接在光层进行数据鉴别和入侵检测的光子防火墙是光网络的一项重要安全技术。在光子防火墙中，二进制序列匹配模块是核心部分，由全光与门、全光异或门等多个全光逻辑门实现。全光逻辑门的缺点是运算率低，导致匹配率低。我们设计了一个二进制序列匹配模块，该模块通过高非线性光纤 (HNLF) 的交叉相位调制效应 (XPM) 和四波混合效应 (FWM) 实现。HNLF的非线性效应具有非常短的响应时间，因此可以在非常高的光信号速率下实现逻辑运算。开发的二进制序列匹配模块通过 VPI Transmission Maker 8.5 验证。仿真结果表明，它可以在160Gbps的信号速率下实现64位二进制数据中8位数据的匹配。
