[WA1] Data Center Interconnection

[WA1-1] Optically-Interconnected Data Center Architectures, Systems, and Enabling Technologies

Tutorial

〇S. J. Ben Yoo (Univ. of California, Davis, USA)

This Tutorial discusses new directions in optically-interconnected data centers driven by the needs for enhancing energy-efficiency, high-throughput, scalability, and manageability. The tutorial will be in three parts. In the architecture section, we will address the controllability and manageability issues of disaggregated systems in light of software-defined control planes, and the need for cross-layer solutions to address application-aware adaptation of physical layers. In particular, we will address the benefits and challenges of photonic layer reconfiguration and switching. The systems section investigates co-optimization of optical and electrical interconnections to facilitate scalability and energy-efficiency. In the enabling technology section, we will study transmitters, receivers, switches, and wavelength routers utilizing silicon photonics with closely integrated electronics, 2.5D and 3D heterogeneous integration, co-packaging, and electronic-photonic-co-design issues. Newly enabled data systems exploiting modular integration of energy-efficient 3D-electronic-photonic-ICs (3D EPICs) and their interconnections through reconfigurable Arrayed-Waveguide-Grating-Routers (AWGRs) will also be discussed.

Bio:S. J. Ben Yoo is a Distinguished Professor at the University of California at Davis (UC Davis). His research at UC Davis includes 2D/3D photonic integration for future computing, cognitive networks, communication, imaging, and navigation systems, micro/nano systems integration, and the future Internet. Prior to joining UC Davis in 1999, he was a Senior Research Scientist at Bellcore, leading technical efforts in integrated photonics, optical networking, and systems integration. His research activities at Bellcore included the next-generation Internet, reconfigurable multiwavelength optical networks (MONET), wavelength interchanging cross connects, wavelength converters, vertical-cavity lasers, and high-speed modulators. He led the MONET testbed experimentation efforts, and participated in ATD/MONET systems integration and a number of standardization activities. Prior to joining Bellcore in 1991, he conducted research on nonlinear optical processes in quantum wells, a four-wave-mixing study of relaxation mechanisms in dye molecules, and ultrafast diffusion-driven photodetectors at Stanford University (BS’84, MS’86, PhD’91, Stanford University). Prof. Yoo is Fellow of IEEE, OSA, NIAC and a recipient of the DARPA Award for Sustained Excellence (1997), the Bellcore CEO Award (1998), the Mid-Career Research Faculty Award (2004 UC Davis), and the Senior Research Faculty Award (2011 UC Davis).
