Ultralow-Power LED-Enabled On-Chip Optical Communication Designed in the III-Nitride and Silicon CMOS Process Integrated Platform

This paper explores the integration of III-V-based LEDs and detectors in a traditional Si-CMOS process to power an on-die nanophotonic link. The work also shows that the LED-enabled on-chip optical link results in more energy-efficient communication than using an off-chip laser source to power the optical link.
