摘要
针对英特尔光峰技术提出了一种非球面微透镜模块的光学优化设计及评价方法。该非球面微透镜模块可经由GGP多模光纤应用于高速数据的传输,非球面微透镜的直径为800μm,数值孔径为0.275。借助光学设计软件Code V及LightTools进行仿真,评估了微透镜模块制造及组装的公差对系统耦合效率的影响,同时考虑了一些影响光功率损耗因素。结果表明,经光学优化设计得到的非球面微透镜模块的耦合损耗为-0.75dB。最后,对于球面微透镜模块和非球面微透镜的性能进行了评价。
An optimized design and evaluation method for an aspherical microlens module was presented for the Intel Light Peak technology.The proposed microlens module can be used for high-speed data transmission via a multi-mode GGP fiber.The aspherical microlens has a small diameter about 800 μm and a numerical aperture of 0.275.By the optical softwares of Code V and LightTools, the effect of fabrication and assembly tolerances of the microlens module on the coupling efficiency was investigated,and some factors related to the optical coupling loss were also considered.After optimization design of the module,an optical coupling loss of-0.75 dB was obtained.Finally,the comparison between the spherical and aspherical microlenses for the optical performance was evaluated.
