对基于半导体光放大器（SOA）中非线性偏振旋转效应（NPR）效应的单一光缓存环多数据包的全光时隙交换（TSI）处理能力进行了理论和实验研究. 在使用归纳法导出单一缓存环实现多数据包全光时隙（TSI）必要条件的基础上，针对各种全光TSI操作要求得出了相应光数据包的调度方案. 在实验上，以基于SOA中NPR效应的单一光缓存环实验系统，开展了多数据包全光TSI操作的实验研究. 根据上述光数据包理论调度方案进行相应系统参数设定，进行了速率为10 Gb/s的3个和4个数据包的全光TSI实验. 实验结果与理论预期相符合. 研究成果为减少昂贵SOA元件的用量、简化基于光缓存环全光TSI系统的结构提供了可靠依据，对推进全光TSI技术的发展具有重要意义.Based on nonlinear polarization rotation (NPR) in semiconductor optical amplifier (SOA), a single optical buffer loop theoretically and experimentally demonstrates its switch capability to realize all-optical time slot interchange (TSI) on multiple optical packets (MOPs). Firstly, a series of prerequisites is theoretically deduced with a single optical buffer loop performing all-optical TSI on MOPs. And the corresponding equations which experimental parameters should satisfy are derived from these prerequisites for different cases of all-optical TSI. Accounting to the theoretical results, a single optical buffer loop based on NPR in SOA experimentally realizes all-optical TSI on three packets and four packets at data rate of 10 Gb/s. Experimental results are in accordance with those expected theoretically. These results will be very helpful to make all-optical TSI system more compact and more highly efficient, and have less expensive elements such as SOA, and also significant for developing the all-optical TSI technology.
