摘要
提出利用级联型双环耦合全光缓存器(DLOB)进行全光时隙处理的方案，并对光分组的时隙压缩、时隙扩展、时隙交换或重排等全光时隙处理功能进行了实验验证。实验结果表明，经过两级DLOB，数据速率为2.448 Gb/s的两个光分组的时间间隔可以在24.3 μs～110 ns之间进行压缩，或在100 ns～26.11 μs之间进行扩展，并且可以达到无误码输出。这种利用级联DLOB对光分组的时隙处理方法，对全光缓存器的研究有一定的参考价值。
Abstract
Based on a cascaded double-loop all-optical buffer (DLOB) structure, a new all-optical slot processing scheme is proposed. The all-optical slot processing functions which include slot compressing, slot expanding and slot interchanging or re-aligning, are proved by experiments. The results demonstrate that the interval between two 2.448 Gb/s optical packets can be compressed from 24.3 μs to 110 ns, or expanded from 100 ns to 26.11 μs by two-level DLOB, and the output optical packets have no bit error. The all-optical slot processing scheme proposed in this paper can provide as a reference for all-optical buffer.
