Abstract

In the 5G era, the demand for high-bandwidth computing, transmission, and storage has led to the development of optoelectronic interconnect technology. This technology has evolved from traditional board-edge optical modules to smaller and more integrated solutions. Co-packaged optics (CPO) has evolved as a solution to meet the growing demand for data. Compared to typical optoelectronic connectivity technology, CPO presents distinct benefits in terms of bandwidth, size, weight, and power consumption. This study presents an overview of CPO, highlighting its fundamental principles, advantages, and distinctive features. Additionally, it examines the current research progress of two distinct approaches utilizing Vertical-Cavity Surface-Emitting Laser (VCSEL) and silicon photonics integration technology. Additionally, it provides a concise overview of the many application situations of CPO. Expanding on this, the analysis focuses on the CPO using 2D, 2.5D, and 3D packaging techniques. Lastly, taking into account the present technological environment, the scientific obstacles encountered by CPO are analyzed, and its future progress is predicted.

共封装光学研究进展。

在 5G 时代，对高带宽计算、传输和存储的需求推动了光电互连技术的发展。这种技术已从传统的板边缘光学模块发展到更小、更集成的解决方案。协同封装光学技术（CPO）已发展成为满足日益增长的数据需求的解决方案。与典型的光电连接技术相比，CPO 在带宽、尺寸、重量和功耗方面具有明显优势。本研究概述了 CPO 的基本原理、优势和特点。此外，本研究还探讨了目前利用垂直腔表面发射激光器（VCSEL）和硅光子集成技术的两种不同方法的研究进展。此外，报告还简要概述了 CPO 的多种应用情况。在此基础上，分析重点关注使用 2D、2.5D 和 3D 封装技术的 CPO。最后，考虑到当前的技术环境，分析了 CPO 所遇到的科学障碍，并预测了其未来的发展。
