摘要
设计并演示了一种新型的光信号全光提取与擦除方案。将两个时域上同步,强度反相的矩形光脉冲作为控制信号,通过光纤中四波混频效应所形成的逻辑门(与门和非门),可以对一段时隙上的光数据进行同步的提取和擦除。对10Gb/s非归零信号的仿真和实验验证了方案的可行性。方案可在更高速率的系统下工作,并对波长和码型透明。
A simultaneous optical signal dropping and cleaning scheme is presented by utilizing four-wave mixing effects based optical logic gate （AND and NOT） in optical fiber. Two synchronized square pulse control signals with inverted intensity, coupled with data stream, produce four-wave mixing effects to implement dropping and cleaning functions. Simulation and experimental results are successfully demonstrated with nonreturn to zero （NRZ） data at 10 Gb/s. The proposal may work at higher bit rate with transparence for operation wavelength and data format.
