摘要
提出一种以基于平行排列3×3耦合器的双环耦合全光缓存器为缓存主体、以非线性光纤环路镜或马赫-曾德尔干涉仪为选择开关的可动态配置延迟的全光缓存器阵列方案。理论与实验证明,该缓存器阵列可实现不同延迟时间的配置,输出信号能满足进一步传输的要求,并可有效降低网络拥塞,减少丢包率。
Abstract
A new all-optical buffer array scheme with dynamic configurable delay time is proposed, in which the dual-loop optical buffer (DLOB) based on 3×3 collinear fiber couplers is the main part and the nonlinear optical loop mirror (NOLM) or Mach-Zehnder interferometer (MZI) is the optical controllable optical switch. Its operation principle is analyzed. The theoretical analysis and experiment demonstrate that delay time can be configurated flexibly, and the signals from the buffer can satisfy the transmission requirement.The proposed optical buffer can eliminate network congestion, and reduce packet loss rate effectively.
