Coherent Transient Processors and Materials
Abstract
Real-time, wide band information storage and signal processing devices are critical to many military and commercial systems in order to perform complex functions such as secure communications, network routing, pattern recognition, electronic surveillance and tracking, database management, and tactical air reconnaissance. Optical coherent transient technology (also referred to as spectral holography) has the potential to perform real-time storage and signal processing at data rates far exceeding 10 EGHz, with storage/pattern densities on the order of a terabit per centimeter squared, and with data block sizes/time-bandwidth products well over 10000. The main objective of the grant was to support the research of two graduate students and augment the research of the parent grants F49620-93-1-0513 and F49620-97-1-0259. The augmented research under these grants included work on true-time delay regenerators, power induced time-shifts, chirped pulse programming of coherent transient true-time-delay devices, recall efficiencies in optically thick media (non-inverted), Coherent transient optical signal processing without brief pulses, Compensation for homogeneous dephasing, and modeling and characterization of gated systems.
