A simple reconfigurable ultrahigh-speed optical device which can be configured to optical NOT, AND, or XOR logic operation via slight variations in the input signals applied to two identical parallel highly nonlinear fibers (HNLFs) is described. The cross-phase modulation (XPM) in the HNLF and phase shifter are used in the design to realize a reconfigurable all-optical logic gate operating at 120 Gb/s. The proposed reconfigurable ultrahigh-speed all-optical logic device could play a crucial role in the realization of future all-optical high-performance flexible optical networks.

高度非线性光纤中基于交叉相位调制的可重构全光逻辑器件的设计

描述了一种简单的可重新配置的超高速光学设备，该设备可以配置为通过施加到两条相同的并行高度非线性光纤（HNLF）的输入信号中的微小变化来进行NOT，AND或XOR逻辑运算。HNLF和移相器中的交叉相位调制（XPM）用于设计中，以实现以120 Gb / s的速度工作的可重构全光逻辑门。拟议的可重构超高速全光逻辑器件在实现未来的全光高性能柔性光网络中将发挥关键作用。
