Integrated Photonics for Energy Efficient Datacenters: The ARPA-E ENLITENED Program
Organizers: Alan Liu, Booz Allen Hamilton, USA; Michael Haney, Advanced Research Projects Agency-Energy, USA
The ARPA-E ENergy-efficient Light-wave Integrated Technology Enabling Networks that Enhance Datacenters (ENLITENED) program seeks to improve datacenter energy efficiency by advancing transformative integrated photonic solutions and co-designed network topologies enabled by the former. This special session will give a comprehensive overview of the ENLITENED portfolio, which includes technologies such as optical switching, co-packaged photonics, and coherent links for the datacenter; as well as network concepts ranging from Clos variants to reconfigurable topologies. ENLITENED kicked off in August of 2017 and targets an overall doubling of datacenter efficiency in 10 years through deployment of the technologies developed in the program.

Due to the rapid progress in the development of quantum computing devices able to decode the most advanced cryptographic algorithms used nowadays, it becomes urgent to develop techniques that protect communication systems at the physical layer level.
The daily operation of businesses, administrations and individuals generating transactions of personal financial and health data, home and vehicle automation information, or cloud computing, is increasingly confronted with the transmission of sensitive data that require protection against threats as well as long-term confidentiality. Cryptographic protocols relying on classical techniques are vulnerable to undetected eavesdropping and to “store now, attack later” attacks. Quantum key distribution (QKD), on the other hand, which is the most prominent quantum cryptographic protocol, allows two remote network nodes to generate an encryption key with information theoretic security.
Since 90% of worldwide communications is done optically (even wireless traffic is transformed into optical signals at the antenna level) and furthermore since QKD and quantum communications in general is implemented using optics, it is only natural to pursue the integration of QKD techniques within standard optical fiber systems and more generally optical transport networks.
In this session, we will discuss:
- Various techniques available to perform QKD (based on encoding of both discrete and continuous properties of light) highlighting the advantages in each case,
- The different trends to proceed to network security through implementation of QKD over optical fibers or through free space optics between satellite and ground stations,
- The means to decrease the cost of current QKD solutions and to make them more compliant with existing optical communication networks, and
- The potential use cases and applications of QKD and quantum communications for service and content providers.
