Space-Time Optical Systems for Ultrahigh-Speed Signal Processing and Encryption
Abstract
Our overall objective is to demonstrate powerful new signal processing functionalities for ultrafast optical signals, with an emphasis on proof-of-concept experiments of new space-time optical processing methods for digital logic operations, especially encryption and temporal pattern matching, on ultrafast optical bit streams. During this project period we focused on an optical space-to-time converter, which is one of the key subsystems in the envisioned space-time optical processing system. For the first time we have worked out how the dispersion varies with the positions of the constituent optical components, and we have verified our analysis experimentally. Our results demonstrate a means for compensating or controlling the chirp of the optical pulse sequences generated from the space-to-time converter, which is important for subsequent transmission in optical networks. Furthermore, our work show the possibility of using these space-to-time converters for generation of identical pulse sequences at a series of different wavelengths, with potential application to optical networks and photonic processing. Finally, for the first time we demonstrated generation of terahertz rate trains of optical pulses using an integrated component, which increases the opportunity for practical applications.
