Workshop Focus

As Moore's Law is slowing down, an exploration of alternative technologies are developed to replace traditional CMOS-based architectures at the heart of data processing. Moreover, stringent application constraints on massive data transfers in data centers, artificial intelligence systems, and embedded high-performance computing (eHPC), requires new communication-centric systems with novel interconnect technologies. Silicon photonics is a prime candidate to achieve this thanks to its compatibility with CMOS fabrication process, scalability, and growing maturity. OPTICS aims at discussing the most recent advances in silicon photonics for computing systems, covering topics from the device fabrication all the way up to the system-level design through circuit optimization with Electronic-Photonic Design Automation (EPDA). The workshop is of interest to researchers working on silicon photonics, high-performance computing systems and EDA/EPDA. It is comprised of invited talks of the highest caliber from industry and academia addressing most recent outcomes. Ideas and new opportunities are discussed during a panel and a refereed poster presentations session highlights works-in progress.

Topics to be discussed include but are not limited to:

  • EPDA (Electronic-Photonic Design Automation): non-uniformity/thermal aware design, floor-planning, crosstalk-aware interconnects modeling and simulation, etc.
  • Inter/Intra-chip Interconnects: hybrid optical-electronic interconnects, passive/active-based optical switched networks, communication protocols, I/O design etc.
  • Applications: embedded high-performance computing, data center, reservoir computing, all-optical logic gates, etc.
  • Silicon Photonics Devices and Circuits: circuit demonstrator, on-chip lasers, photodetectors, electro-optic modulators, optical switches, athermal devices, etc.
