Reconfigurable Computing with Nanophotonics
With the end of the Moore’s law and Dennard Scaling, new post-Moore’s law processing paradigms are sought. Nanophotonic devices are characterized by being ultralow power. Harnessing the new developments in material science, many of such devices were created and shown to be capable of performing analog and digital computations that can address a range of applications. Such nanophotonic devices are intrinsically reconfigurable thereby offering a very powerful computational alternative which combines low power, reduced sizes, speed and reconfigurability. They also offer a great deal of parallelism through wavelength division multiplexing (WDM). While substantial progress has been made and there are notable successes, many technological challenges remain. In this talk we will present a range of novel photonic analog and digital reconfigurable computer architectures to solve important problems with applications, including but not limited, to partial differential equations, which form the basis for many scientific and engineering computations, and deep neural networks for machine learning. We also characterize some of the successes and the remaining research challenges.
