Integrated Photonics for Energy Efficient Data Centers and Computing: The ARPA-E ENLITENED Program

Monday, 07 March 10:30 – 12:30

The ARPA-E ENergy-efficient Light-wave Integrated Technology Enabling Networks that Enhance Dataprocessing (ENLITENED) program seeks to improve HPC and data center energy efficiency by advancing transformative integrated photonic technologies for data transmission and switching to enable novel co-designed network topologies.  This special session will provide a comprehensive overview of the ENLITENED portfolio, which includes technologies such as optical switching, co-packaged photonics, and coherent links for the data center; as well as network concepts ranging from Clos variants to reconfigurable topologies. The program has entered its final year, with activities primarily centered on prototype maturation and demonstration, while ensuring that critical design features of the full-scale system can be validated and de-risked. The overall goal of the program is to enable photonic network fabrics which, when deployed at scale, would realize an overall doubling of system-level efficiency.
