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 optical optimization design and evaluation method for aspheric microlens module are proposed for Intel Light Peak Technology. The aspherical microlens module can be applied to high-speed data transmission via GGP multimode fiber, the aspheric microlens has a diameter of 800 μm and a numerical aperture of 0.275. With the aid of the optical design software Code V and LightTools, the influence of the manufacturing and assembly tolerance of the microlens module on the system coupling efficiency was evaluated, and some factors affecting the optical power loss were considered. The results show that the coupling loss of the aspherical microlens module obtained by optical optimization is -0.75dB. Finally, the performance of the spherical microlens module and aspheric microlens was evaluated.
