The performance of electro-optic modulators and optical routers and their routing algorithms are the key factors affecting the performance of networks on optical chips. This paper improves the mesh 3-dimensional photonic network-on-chip (3D-PNoC) topology. An SPP hybrid silicon-based electro-optic modulator and an improved fault-tolerant SPP router are used to improve the performance of the network on an optical chip. SPP switching and SPP MRR are combined to form a fault-tolerant SPP router. On this basis, an improved genetic optimization routing algorithm is implemented on the improved mesh 3D PNoC topology, which completes the data exchange of the IP core of the network on the optical chip. Compared with the case of traditional optoelectronic devices, the performance of on-chip optical networks can be improved effectively. The simulation results show that upon the application of the improved genetic optimization routing algorithm to the improved mesh 3D PNoC topology, the average end-to-end delay is reduced by 32.9%, the throughput rate is increased by 28.5%, and the system power consumption is reduced by 27.6%. On the other hand, the average insertion loss and noise of optical routers are increased by 2.94 dB and 2.95 dB, respectively.
电光调制器和光路由器的性能及其路由算法是影响光芯片上网络性能的关键因素。本文改进了网状三维光子片上网络（3D-PNoC）拓扑结构。使用表面等离激元极化激元（SPP）混合硅基电光调制器和改进的容错SPP路由器来提高光芯片上网络的性能。将SPP交换和SPP微环谐振器（MRR）相结合，形成一个容错SPP路由器。在此基础上，在改进的网状3D PNoC拓扑结构上实现了一种改进的遗传优化路由算法，完成了光芯片上网络IP核的数据交换。与传统光电器件的情况相比，可以有效提高片上光网络的性能。仿真结果表明，将改进的遗传优化路由算法应用于改进的网状3D PNoC拓扑结构时，平均端到端延迟降低了32.9%，吞吐率提高了28.5%，系统功耗降低了27.6%。另一方面，光路由器的平均插入损耗和噪声分别增加了2.94 dB和2.95 dB。
