| 中文摘要 | 采用相干隧穿破坏(CDT)理论和自囚禁(self-trapping)效应相结合的方法实现光信号的交叉连接功能.在标量场和傍轴近似下,进一步采用紧束缚近似,得到周期性调制光纤中光信号传播的耦合模方程组.只考虑相邻光纤耦合作用情况下,数值模拟全光交叉连接功能实现过程并获得各种变换所需条件.在器件输出端引入可调谐滤波器可实现光信号的广播发送、光路变换和上下路等功能,能推广到任意N×N光交叉连接设计中,有效地解决波分复用光网络中光信号时延和容量需求问题.; Based on a method combining coherent destruction of tunneling( CDT) theory and self-trapping effect,a scheme realized all-optical transform. In scalar field and paraxial approximation,and by using tight binding approximation,we derived coupled mode equations of optical signal propagation in periodic modulated optical fibers. Considering coupling effect of adjacent fibers,we realized all-optical transform function numerically and conditions required were obtained. With introduction of tunable filter at output side,broadcast transmitting,optical transformation and drop /on functions are realized with an 8 �8 optical cross connector,which can be extended to N �N optical cross connector. It can be used to solve problems of signals delay and capacity requirements in WDM optical networks. |
