Session Title: Delivering Data to the Point of Compute with Silicon Photonics Abstract: Package bandwidth requirements for various data-center processing units (XPUs) are increasing exponentially, as ever-larger and more complex artificial intelligence (AI) models are developed and deployed. These processors need low-power, high-bandwidth, and low-latency links not only to other processors in the compute network but also to external memory resources. Optical networks are ideally suited to fulfill these connectivity requirements and several solutions, ranging from front-panel optics to 2.5D/3D integrated silicon photonics, are at different stages of productization. But in all these solutions, the bandwidth accessible to the XPU is limited to its beachfront, since all these architectures bring the optics only as far as the edge of the ASIC due to thermal and area constraints. To fully unlock the potential of optical interconnects and get to the next generation of package bandwidths, the photonics need to go beyond the processor beachfront and deliver data right to the point of compute. This talk presents a full-stack silicon photonics-based platform that provides such connectivity, enabled by very high areal density of the I/Os and exceptional temperature stability of the optics, Bio: Subal Sahni is the Sr. Director of Photonics at Celestial AI. Subal has over 15 years ofexperience in the development and productization of integrated optics and brings a deep understanding of all phases of the engineering lifecycle of these products, from design to high volume manufacturing. Previously he was Sr. Technical Leader at Cisco Systems where he led the integration engineering group in the Luxtera division. Subal came to Cisco through the acquisition of Luxtera Inc, a pioneer in the design and commercialization of Silicon Photonics. A Senior Principal Engineer at Luxtera, he was a seminal part of the technology team that enabled the first high volume Silicon Photonics products in the optical transceiver industry. Subal received the B. Tech. degree in engineering physics from the Indian Institute of Technology Bombay, India, and the M.S. and Ph.D. degrees in electrical engineering from the University of California, Los Angeles. He has been granted more than 20 patents on various aspects of technology and product development using Silicon Photonic
