In this video, Fuad Doany from IBM T. J. Watson presents: Power-Efficient, High-Bandwidth Optical Interconnects for High Performance Computing.
High performance computing systems are driving development and large-scale deployment of parallel optical interconnects to meet the ever-increasing interconnect bandwidth requirements. We have demonstrated generations of chip-scale transceivers, or “Optochips”, with record setting high-speed, high-density, and low-power performance. Optical interconnects and Si-photonic communication still present significant technical challenges for future exa-scale supercomputers. Optical interconnect technology must continue to evolve to meet future bandwidth demand, including order of magnitude improvements in cost, power, density, and reliability. Integrated low-power parallel transceivers, optical printed circuit boards and silicon based integrated photonics are potential technologies to meet these challenges.”
