我们展示了一种新颖的无源全光R-S触发器的设计，该触发器基于光纤布拉格光栅（fbg）中的非线性，具有单独的静置端口。研究了克尔效应下FBGs的谱，并通过对耦合模方程的数值求解，研究了无源分布反馈结构非线性双稳性的连续波和瞬态特性。结果表明，脉冲宽度为0.15 ns的脉冲可以切换触发器的状态。
We demonstrate a novel design for a passive all-optical R-S flip-flop with separate set-rest ports based on nonlinearity in the fiber Bragg gratings (FBGs). The spectrum of FBGs in the presence of the Kerr effect is investigated, and cw and transient characteristics of nonlinear-induced bistability of the passive distributed feedback structures are studied by numerical solving of coupled-mode equations. It is shown that a pulse with a pulsewidth of 0.15 ns can switch the state of the flip-flop.
