A 6V Swing 3.6% THD >40GHz Driver with 4.5× Bandwidth Extension for a 272Gb/s Dual-Polarization 16-QAM Silicon Photonic Transmitter

📋 论文概要

本文提出一种用于硅光子相干通信的驱动器，实现了6V摆幅、3.6% THD和超过40GHz带宽，通过4.5倍带宽扩展技术，支持272Gb/s双偏振16-QAM调制。解决了传统LiNbO3调制器和III-V驱动器体积大、不适合高容量数据中心的问题。

💡 主要创新点

• 采用带宽扩展技术实现4.5倍带宽提升，同时保持高线性度（3.6% THD）和大摆幅（6V）。
• 在硅光子平台上集成高性能驱动器，替代传统的LiNbO3和III-V方案，实现紧凑、高容量的相干光发射机。

While delivering high bandwidth (BW) and linearity, such a platform is bulky and does not work for high-volume or intra-datacenter applications. Silicon photonics (SiPh) offers a Si-based platform for next-generation transceivers by integrating all required optical functions. But even in existing SiPh-based commercial modules, the driver generally remains a III-V-based chipset, impeding the path to an all-silicon solution.
