随着大型高能物理实验、空间实验的不断发展，探测器前端数据传输的总带宽不断攀升，读出环境对于电子学在体积、功耗和抗辐射方面的要求也不断提高。适应于未来高能物理需求的高速数据传输方案将成为前端数据读出的基础架构之一。基于VCSEL Array的并行光纤数据传输模块在抗辐射、高密度、高带宽方面的优势，逐渐成为下一代高能物理前端数据传输的首选。本项目将着手模块设计与激光器驱动ASIC设计两方面，一方面研发解决模块高密度、高速电接口设计及光接口耦合装配、抗辐射验证等关键难点。另一方面着手抗辐射激光器驱动ASIC领域，设计一款4 ch x 14 Gbps/ch抗辐射激光器驱动芯片，其与模块结合将达成国内高能物理首个从芯片到模块全定制的56 Gbps抗辐射并行光模块，并完成测试。同时进一步对脉冲幅度调制(PAM4)技术进行前瞻性研究，设计高能物理领域第一款抗辐射20 Gbps PAM4激光器驱动芯片。

With the booming developments of high-energy physics experiments, space experiments and new detectors, the data rates proposed for font-end readout electronics is foreseen to increase exponentially. And these specific readout environments also impose additional requirements for the front-end data transmission systems in terms of the form factor, the power consumption and the radiation-tolerance. 850 nm VCSEL array based parallel optical transmitter, featuring the advantages of high-bandwidth, high-density and radiation-tolerance, has become the most potential candidate for the data transmission in the next-generation high-energy physics experiments. This project will propose the development of a fully-customized, radiation-tolerant, parallel optical transmitter from two steps. Firstly, key issues of the module-level development, including high-speed electrical/optical interface designs, array optical component alignment/assembly and radiation-tolerance verification, will be solved. Secondly, a 4 ch x 14 Gbps/ch radiation-tolerant VCSEL Array driver will be designed. After integrated within the customized array optical transmitter, the whole module of 4-ch x 14 Gbps data capability will be the first fully-customized, radiation-tolerant array optical module for the domestic high-energy physics experiments. As a continuous research on VCSEL driver ASIC design, a PAM4 VCSEL driver will also be proposed, designed and tested. And this will be the first time that a PAM4 VCSEL driver ever designed for the high-energy physics experiment.
