数万 GPU 为何仍需等待？SK hynix 解析硅光子与 CPO 如何构筑“光的高速公路”
[Tech Note] Why does AI still have to wait with tens of thousands of GPUs? How silicon photonics and CPO are building the ‘highways of light’
AI 导读
硅光子技术通过光纤将光导入硅基光子集成电路（PIC），在芯片内由环形谐振器、调制器和光电探测器等集成元件控制光，实现电信号与光信号的相互转换。SK hynix 发文解析，这类硅光子技术与 CPO（共封装光学）正是缓解大规模 GPU 集群数据传输瓶颈的“光的高速公路”。

▲ Silicon photonics directs light entering through an optical fiber into waveguides within a silicon photonic integrated circuit (PIC), where integrated components such as ring resonators, modulators, and photodetectors control the light. Within this small chip, electrical signals can be encoded onto light, while incoming light can be converted back into electrical signals to retrieve the information.
