Recent developments in transceiver SoC design for next generation optical networks

Abstract

This paper presents the ongoing research efforts in optical communication transceiver SoC design for emerging fiberwireless mobile networks and next generation 200/400GbE optical networks using advanced CMOS technologies. First, a 4-Gb/s fiber-to-mm-wave baseband-over-fiber (BoF) modulator SoC using 65-nm CMOS with a fully integrated 850-nm wavelength optical receiver front-end for short-range wireless backhaul connectivity is reviewed. Next, design considerations for an improved 10-Gb/s BoF I/Q modulator SoC with integrated 60-GHz power amplifier is described. Lastly, a novel PAM4/NRZ transceiver architecture featuring BER built-in-self-test is discussed.
