Intel Demonstrates Industry-First Co-Packaged Optics Ethernet Switch

Today Intel announced that it successfully integrated its 1.6 Tbps silicon photonics engine with its 12.8 Tbps programmable Ethernet switch. The co-packaged switch optimized for hyperscale data centers brings together the essential technology building blocks from Intel and its Barefoot Networks Division. Our co-packaged optics demonstration is the first step to making optical I/O with silicon photonics a reality,” said Hong Hou, Intel corporate vice president and general manager of the Silicon Photonics Products Division. “We share the industry belief that co-packaged optics offers power and density advantages for switches at 25 Tbps and higher, and ultimately is a necessary and enabling technology for bandwidth scalability in future networks. The timing of this demonstration shows the technology is ready to support our customers’ requirements.”

New Paper: Nanophotonic Neural Networks coming Closer to Reality

Over at the Intel AI blog, Casimir Wierzynski writes that Optical Neural Networks have exciting potential for power-efficiency in AI computation. “At last week’s CLEO conference, we and our collaborators at UC Berkeley presented new findings around ONNs, including a proposal for how that original work could be extended in the face of real-world manufacturing constraints to bring nanophotonic neural network circuits one step closer to a practical reality.”

Video: Silicon Photonics for Extreme Computing

Keren Bergman from Columbia University gave this talk at the 2017 Argonne Training Program on Extreme-Scale Computing. “Exaflop machines would represent a thousand-fold improvement over the current standard, the petaflop machines that first came on line in 2008. But while exaflop computers already appear on funders’ technology roadmaps, making the exaflop leap on the short timescales of those roadmaps constitutes a formidable challenge.”
