Research on Detection Method of Bridge Fault Number in Optical Router

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.
