2月18日，北京大学电子学院、鹏城实验室、上海科技大学、国家信息光电子创新中心等研究团队在《自然》（Nature）发表论文《集成光子学赋能超宽带光纤-无线通信》（Integrated photonics enabling ultra-wideband fibre–wireless communication），报告他们采用集成光学方案，实现了250GHz以上超大带宽的光电/电光转换器件，薄膜铌酸锂调制器（TFLNMZM）和磷化铟探测器（InP UTC-PD）带宽均创纪录；同时，基于上述器件实现了“光纤-无线一体化融合”系统演示，光纤通信实现破纪录的单通道256Gbaud（512Gbps）信号传输，太赫兹无线通信实现破纪录的单通道400Gbps信号传输，并完成了86路8K高清实时视频的无线传输演示。。WPS官方版本下载对此有专业解读
The FTSE 100 is sailing ever higher on a big wave of enthusiasm for London listed stocks. The blue-chip index has opened at fresh record levels. It’s been on a breathtaking run upwards, accelerating its surge higher since the start of the year, rising by more than 9%. Momentum appears to be on its side with the psychologically important 11,000 mark now in its sights. Its mining constituents have been benefitting for demand for metals in particular, as signs indicate that a commodities super-cycle is underway, with huge demand for metals and minerals needed to power the green revolution and build AI infrastructure. Geopolitical tensions and rising debt levels are keeping demand for safe precious metals intact, while defence contractors continue to benefit from the big uplift in spending on military capabilities.，推荐阅读91视频获取更多信息
