Abstract:

Large-scale high-performance computing is permeating nearly every corner of modern applications spanning from scientific research and business operations, to medical diagnostics, and national security. All these communities rely on computer systems to process vast volumes of data quickly and efficiently, yet progress toward increased computing power has experienced a slowdown in the last number of years. The sheer cost and scale, stemming from the need for extreme parallelism, are amongst the reasons behind this stall. In particular, very large-scale, ultra-high bandwidth interconnects, essential for maintaining computation performance, represent an increasing portion of the total cost bud get. Here, photonic systems are often cited as ways to break through the energy bandwidth limitations of conventional electrical wires toward drastically improving interconnect performance. This talk presents an overview of the challenges associated with optical interconnects, and reviews how photonic technologies can contribute to addressing these challenges.
