摘要
提出了一种新型非反转归零(RZ)码的可重构全光逻辑门方案。该方案基于单个半导体光放大器(SOA)和可调谐光带通滤波器(TOBPF)。利用SOA的四波混频效应和交叉增益调别(XGM)效应，实现了RZ码信号的多种功能逻辑运算。在不改变实验装置的情况下，通过调节带通滤波器中心波长和信号光功率，可以在不同逻辑功能之间进行切换。实验实现了10 Gb/s全光信号间的“与”,“非”,“或非”,“同或”,“·B”,“A·B”等基本逻辑运算。与用连续光作为探测光不同的是，本方案采用了时钟信号作为探测光，这样各个逻辑门的输出均为非反转RZ码，有利于不同逻辑门的进一步组合。
Abstract
A reconfigurable all-optical logic gates with not-inverted data technique is demonstrated by using a single semiconductor optical amplifier (SOA) and a tunable optical band-pass filter (TOBPF). Based on cross-gain modulation (XGM) and four-wave mixing (FWM) in the SOA, multiple Boolean calculation of the return-to-zero signal is realized, and different logical functions are switched by adjusting band-pass filter center wavelength and optical signal power. In the experiment, all-optical multiple logic gates of AND, NOT, NOR, NXOR,·B, and A·B functions at 10 Gb/s are demonstrated without changing the experimental setup. In order to obtain not-inverted RZ data, the clock signal is used for the probe signal which is benefit to combining the basic logics to complicated logic gates.
