在未来的光分组交换网络中，光缓冲器对于光信号处理至关重要。在这封信中，我们提出了一种基于3/SPL倍/3共线光纤耦合器的双环光纤缓存器。DLOB结构紧凑，开关操作所需的控制功率低。缓冲器中只有一个开关用于“写入”和“擦除”操作。首先给出了100Mb/S光分组存储的实验结果，然后将其容量进一步扩展到2.5 Gb/S的较高数据速率，在两种情况下都观察到了超过32个循环的存储。
Optical buffers are critical for optical signal processing in future optical packet-switched networks. In this letter, we present a dual-loop optical buffer (DLOB) that is based on a 3 /spl times/ 3 collinear fiber coupler. A DLOB has compact structure and needs low control power for switch operation. There is only one switch in the buffer for both "write" and "erase" operation. The experiment results of storage of optical packets at 100 Mb/s is presented first and then its capacity is extended further to higher data rates of 2.5 Gb/s. Storage has been observed for more than 32 circulations in both cases.
