This letter reports on a 108-GHz bandwidth 0.5- $\mu \text{m}$ InP DHBT analog-multiplexer-driver (AMUX-driver). To the best of the authors’ knowledge, this 2:1 AMUX-driver shows unprecedented 1.9-Vppd 160-GSa/s 160-GBd non-return-to-zero (NRZ) and 2.4-Vppd 100-GSa/s 100-GBd PAM-4 output swings, with very high-quality eye diagrams, without any digital signal processing (DSP) or postprocessing. Up to 3.2 Vppd is obtained in NRZ at 100 GBd. The lumped AMUX-driver also shows record 25.7-dB gain and 2.08-THz gain-bandwidth product with 11.1-dB equalizing capabilities at 86.6 GHz.

用于下一代光通信的 160GSa/s 和超过 108GHz 带宽超过 2Vppd 输出摆幅 0.5μm InP DHBT 2:1 AMUX 驱动器

这封信报告了 108-GHz 带宽 0.5- $\mu \text{m}$InP DHBT 模拟多路复用器驱动器(AMUX 驱动器)。据作者所知,这款 2:1 AMUX 驱动器显示出前所未有的 1.9-V ppd 160-GSa/s 160-GBd 不归零 (NRZ) 和 2.4-V ppd 100-GSa/s 100-GBd PAM-4 输出摆幅,具有非常高质量的眼图,无需任何数字信号处理 (DSP) 或后处理。在 100 GBd 的 NRZ 中获得高达 3.2 V ppd 。集总 AMUX 驱动器还显示出创纪录的 25.7-dB 增益和 2.08-THz 增益带宽积,在 86.6 GHz 时具有 11.1-dB 的均衡能力。
