摘要

一种双段硅光子微环调制器实现了用于PAM4调制的光DAC。使用分段的MSB/LSB脉冲级联码驱动器实现独立的电平和边率控制。65nm CMOS发射器以4.38mW/Gb/s的速度实现40Gb/s的运行，同时以4.4Vppd的摆幅驱动每个微环调制器段。

A two-segment optical DAC 40 Gb/s PAM4 silicon microring resonator modulator transmitter in 65nm CMOS

A two-segment silicon photonic microring modulator implements an optical DAC for PAM4 modulation. Independent level and edge-rate control is achieved using segmented MSB/LSB pulsed-cascode drivers. The 65nm CMOS transmitter achieves 40Gb/s operation at 4.38mW/Gb/s while driving each microring modulator segment with 4.4Vppd swing.
