本文提出了一种基于VCSEL的直接驱动光学引擎，采用PAM-4调制实现108Gb/s的数据速率，能效为0.9pJ/b。通过消除重定时器或DSP，直接连接计算系统与光学引擎，解决了可插拔光模块的功耗和可扩展性挑战。
applications necessitates advancements in data transmission. Increasingly complex, power-hungry equalization and digital signal processing (DSP) techniques limit electrical interconnect scalability and reach. Pluggable optical modules extend the reach, but at the cost of scalability/power challenges, due to their integrated re-timer (or DSP) which cleans up the received signal before sending it to the optical engine (OE). By directly connecting computing (XPU) systems to OEs, emerging co-packaged optics (CPO) [1-2] can address these challenges by eliminating the re-timer. Multi-mode vertical-cavity surface-emitting lasers (VCSELs) continue to improve their performance and enable high-BW connectivity over a few tens of meters [1-2] in conjunction with high
