Advanced Coherent Transient Systems
Abstract
Real-time, wide band information storage and signal processing devices are critical to many military and commercial systems. Optical coherent transient technology has the potential to perform real-time storage and continuous signal processing at data rates up to a terahertz, with storage/pattern densities on the order of a terabit per centimeter squared, and with data block sizes/time-bandwidth products well over 10000. These attributes coupled with spatial selectivity and the ability to process amplitude, phase, and frequency modulated signals makes coherent transients an extremely versatile technology. Applications include target and pattern recognition; multi-dimensional cache memory; high density, high bandwidth database memory, associative memory, and look-up tables; secure communications; interior memory for optical networks; real-time address decoder; all optical passive routing of data; header stripper/isolator for network packets; and dynamic pulse shaping and distortion compensation. The research under this grant included work on true-time delay regenerators, power induced time-shifts, chirped pulse programming of coherent transient true-time-delay devices, orthogonal code development, recall efficiencies in optically thick media (non-inverted) and inverted media, modeling and characterization of gated systems, and routing and processing of optical waveforms with structured surface gratings. The grant was terminated after one year due to Prof. Babbitt's move to Montana State University.
