Описание: Talk Title: "Artificial Intelligence at the Speed of Light"

Abstract: The massive data deluge from mobile, IoT, and edge devices, together with powerful innovations in data science and hardware processing have established artificial intelligence (AI) as the cornerstone of modern medical, automotive, industrial automation, and consumer electronics domains. Domain-specific AI accelerators now dominate CPUs and GPUs for energy-efficient AI and machine learning processing. However, the evolution of these electronic accelerators is facing fundamental limits due to the slowdown of Moore’s law and the reliance on metal wires, which severely bottleneck computational performance today. Silicon photonics represents a promising technological alternative to overcome these limitations. Not only can photonic interconnects fabricated in CMOS-compatible processes provide near speed of light transfers at the chip-scale, but photonic devices can now also perform computations entirely in the optical domain. In this talk, I will present my vision of how silicon photonics can drive an entirely new class of sustainable AI hardware accelerators that can provide orders of magnitude energy improvements over today’s accelerators. I will discuss the evolution of silicon photonics, from integrated optics to photonic devices that can now be fabricated with low-cost CMOS-compatible manufacturing techniques. I will cover new directions in the design of robust and secure photonic substrates for communication, computation, and storage to support emerging AI applications based on LLMs, graph processing, and generative modeling. I will share experiences from my journey over the past two decades towards realizing viable silicon photonic architectures. I will end the talk with a discussion of the EDA related and other challenges to achieve unparalleled energy-efficiency and performance gains in future computing platforms with silicon photonics.
