| 摘 要： | 建立了板级光互连模块有限元分析模型,对其进行温度载荷下的有限元分析,分别获取了垂直腔面发射激光器（VCSEL,vertical cavity surface emitting laser）与耦合元件、耦合元件与光波导两个关键位置处在不同温度时刻的轴向、水平和垂直方向的对准偏移。结果表明：光互连模块关键位置的部件在温度载荷下会产生轴向、水平和垂直方向的对准偏移;在一个温度载荷周期内位置偏移值随着温度变化而变化,其中在低温保温阶段对准偏移值最大,在高温保温阶段对准偏移最小;在低温阶段关键位置处的轴向位置偏移最大,并且12路光通道中水平位置偏移呈现两端偏移大,中间偏移小的趋势。

| Abstract: | The finite element analysis models of optical interconnection model are developed,whose finite element is analyed under temperature load. The alignment offsets between vertical cavity surface emitting lase（ VCSEL） and coupling element and the alignment offsets between coupling elements and optical waveguide in different time in a thermal cycling are acquired. The results of study show that the key part of the coupling position will generate alignments during the temperature load cycling. The alignment changes with temperature change in a cycling. The alignment offset has the maximum value in low-temperature stage and minimum value in high-temperature stage. In low-temperature,the axial direction alignment offset of the middle optical channel is lower than the two end optical channel. |
