摘要
随着硅-光技术的突破,光片上网络系统相比传统的片上系统具有更优的性能。微环谐振器(micro ring resonators,MRR)是组成光路由器的核心器件,因温度影响或制造缺陷,MRR极易发生谐振波长的漂移,从而引起器件的桥接故障,降低光片上网络系统的安全性和可靠性。文中建立了MRR桥接故障模型,提出了光路由器桥接故障数量检测方法,首先将光路由器中的微环谐振器进行分类,依次建立3种光路寻找结构,得到3条桥接故障寻找路径,找到每条光路径下对应的可以构成桥接故障的微环谐振器。实验结果证明了文中设计的故障数量检测方法的有效性。
With the breakthrough of silicon optical technology,photonic network on chip system has better performance than traditional system on chip.Micro ring resonators(MRR)are the core components of optical router.Due to temperature effect or manufacturing defects,MRR are prone to shift the resonant wavelength,which leads to device bridge fault and reduces the security and reliability of network on chip system.In this paper,the MRR bridge fault model was established,and the detection method of bridge fault number in optical router was proposed.Firstly,the MRR in optical router were classified,three kinds of optical path searching structures were established in turn,and three bridge fault searching paths were obtained,and then the corresponding MRR in each optical path that can constitute bridge fault were found.The experimental results show that the proposed method is effective.
