Optical/Photonic Interconnects for Computing Systems


OPTICS 2018

March 23rd 2018, Dresden Germany
In Conjunction with Design, Automation & Test in Europe Conference

Multiprocessors have become the standard for high-performance computing systems. The performance of multiprocessors is determined not only by the performance of its processing cores, memories, and peripherals but also by how efficiently they collaborate with one another. As the technology advances and allows the integration of many processing cores, memories, and peripherals, electrical interconnects are becoming a bottleneck due to high energy consumption, high latency, and limited bandwidth. Recent years, photonic technology has demonstrated promising potentials to address these issues. In this context, high-performance silicon photonic devices and circuits are necessary to construct photonic interconnect networks. Furthermore, it is required to explore the feasibility and performance of photonic interconnects as well as the guidelines and design requirements to realize such interconnects. OPTICS aims at discussing the most recent advances in photonic interconnect and silicon photonics for computing systems. Industry’s and academia’s views on the feasibility and recent progress of optical interconnect and silicon photonics will be discussed. The workshop is comprised of invited talks of the highest caliber in addition to refereed poster presentations.
