摘要

在光子防火墙中，为了实现能够有效处理高速光信号的全光模式匹配技术，针对BPSK信号提出了一种信号速率高达42 Gbit/s的全光模式匹配系统，并采用商用器件进行了实验验证。首先，通过给BPSK输入序列分别添加同相和反相的相干载波将BPSK信号转换为2个互为反向的强度调制（IM）信号；然后，通过延时线和由高非线性光纤（HNLF）实现的光学AND门进行相关操作；最后，输出表征全光模式匹配结果的高电平脉冲。仿真和实验结果表明，所提系统可以在8位的42 Gbit/s BPSK输入序列中识别出4位目标序列，验证了BPSK信号的全光模式匹配的可行性，适用于高速光子防火墙。

Abstract

To achieve the all-optical pattern matching for optoelectronic firewall which could process high-speed optical signals efficiently

a BPSK all-optical pattern recognition system with the data rate up to 42 Gbit/s was proposed and demonstrated by employing the commercial optical components.First

the input BPSK sequence was converted to a positive and a negative IM signals by adding in-phase and inverse-phase coherent carriers

respectively.Then the converted IM signals were coupled into time delay lines and optical AND logic gates implemented by HNLF to achieve the optical correlation operation.In the end

a high-level optical pulse indicating the pattern matched result was output.The numerical simulation and the experiment results demonstrate that the proposed system can recognize a 4-bit target BPSK sequence from an 8-bit 42 Gbit/s BPSK input sequence

which proves the feasibility of the all-optical pattern matching of BPSK signals and can be applied to high-speed optoelectronic firewall.
