Abstract

Silicon photonics is a key-enabling technology leveraging decades of effort and infrastructure of the microelectronics CMOS industry resulting in high yield, low cost and potential high volume manufacturing. Furthermore, due to the high index contrast of the platform, very compact, high-complexity photonic integrated circuits can be devised.To benefit fromthese advantages, high-speed modulators should also be compatible with silicon technology. In this respect, SiGe electro-absorptionmodulators (EAM) are considered as a promising candidate since they are CMOS-compatible and offer high-speed, compact, low-loss and low-power modulation. In this paper, we discuss SiGe EAM-based transceivers for next-generation datacenter interconnects (DCI) and radio-over-fiber (RoF) fronthaul in next-generation cellular networks.
