摘　　要：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 network-on-chip （ONoC） has many characteristics superior to electrical interconnection and has emerged as a promising alternative. To improve the performance of optical on-chip networks, a novelring-based 4 x 4 nonblocking silicon optical router was proposed by means of optical module method. This structure just composes evenmicroring-resonator-based switching elements and six waveguide crossings, which reduce power consumption, device area and insertion loss. Finally, the topology performance were evalutated in terms of insertion loss and power consumption. The simulation results demonstrate that the proposed architecture consumes 8% less power and 7% less optical insertion lOSS.
