摘要

采用250 nm InP双异质结双极晶体管(dhbt)，首次实现了超宽带2:1模拟多路复用器(AMUX)单片集成光调制器驱动器，具有创纪录的带宽。制造的驱动集成的AMUX (AMUX- driver) IC具有超过110 GHz的数据路径带宽和10.5 dB的数据路径增益。利用该AMUX-Driver IC实现了160 g波特级基带信号生成。此外，还开发了一个紧凑的集成光前端模块，该模块集成了AMUX-Driver IC和基于inp的光I/Q调制器，具有80 GHz的6 db电光(EO)带宽。利用该集成模块成功实现了基于168gbaud偏振分复用(PDM) 16进制正交调幅(16-QAM)的超1tb /s载波光调制。

A 110-GHz-Bandwidth 2:1 AMUX-Driver using 250-nm InP DHBTs for Beyond-1-Tb/s/carrier Optical Transmission Systems

This paper presents the first ultra-broadband 2:1 analog multiplexer (AMUX) monolithically integrated with an optical modulator driver with the record bandwidth using 250-nm InP double heterojunction bipolar transistors (DHBTs). The fabricated driver-integrated AMUX (AMUX-Driver) IC has a data-path bandwidth of over 110 GHz and a data-path gain of 10.5 dB. A 160-GBaud-class baseband signal generation has been achieved by using this AMUX-Driver IC. In addition, a compact integrated optical front-end module with a 6-dB electro-optic (EO) bandwidth of 80 GHz, incorporating the AMUX-Driver ICs and an InP-based optical I/Q modulator, has been developed. We have successfully demonstrated a beyond-1-Tb/s/carrier optical modulation based on 168-GBaud polarization division multiplexed (PDM) 16-ary quadrature amplitude modulation (16-QAM) by using this integrated module.
