Title: Digital Optical Computation for High-Speed Networking

Abstract:
High-speed networking requires optical encoding, which drives the need for digital optical computation. The Optical Turing Machine (OTM) is our effort to design and implement a digital device that computes using multibit optical symbols. Its goal is to support high-speed computation using an encoding capable of high-speed long-distance transmission. OTM explores the unification of communication and computation, and investigates the nature of Turing-equivalent computation. This talk presents the OTM concept and discusses its key challenges. We discuss our current OTM projects, including the extension of our earlier all-optical packet hopcount decrement to multibit encoding, and the design and implementation of the world's first all-optical Internet checksum.
