Silicon photonics: Energy-efficient communication
TLDR
Silicon photonics that utilizes scalable CMOS technology may offer a highly integrated photonics transmission platform for such applications as data centres and telecommunications networks.Abstract:
Scaling IT infrastructure from microscale processors to macroscale data centres and telecommunications networks requires high-bandwidth technologies that are cheap, low-power and small. Silicon photonics that utilizes scalable CMOS technology may offer a highly integrated photonics transmission platform for such applications.read more
