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 new type of optical signal extraction and erasing scheme is designed and demonstrated. Using two rectangular light pulses with synchronous and intensity inversion in the time domain as the control signal, the optical data (AND and NOT) formed by the four-wave mixing effect in the optical fiber can perform optical data on a time slot Synchronous extraction and erasure. The simulation and experiment of 10Gb / s non-return to zero signal verify the feasibility of the scheme. The solution works at higher rate systems and is transparent to wavelength and pattern.
