光互连技术因诸多特性优于电互连而成为片上多核互连最具前景的解决方案。为了提高片上光互连网络架构的性能,采取光器件模块搭建的方法,提出了一种基于微环的新型4×4光路由开关,仅用7个微环构建的拓扑结构便实现了4个双向端口的非阻塞交换,降低了功耗和面积;波导交叉的数量减少到6个,优化了插入损耗。结果表明,该结构相对于经典结构光器件的功耗节省了约8%,光互连层的插入损耗降低了约7%。 Optical interconnect technology is the most promising solution for on-chip multi-core interconnects because of its many advantages over electrical interconnects. In order to improve the performance of the on-chip optical interconnection network architecture, a novel 4 × 4 optical routing switch based on microring is proposed by taking the construction of the optical device module. Four topologies with only seven microring are realized Non-blocking switching of bidirectional ports reduces power consumption and area; the number of waveguide crossovers is reduced to six, optimizing insertion loss. The results show that this structure saves about 8% of the power consumption of a typical structured light device and reduces the insertion loss of the optical interconnection layer by about 7%.
