Abstract : The main objective of the program was to determine if and where coherent transient technology can be used in future memory and signal processing devices, to develop techniques for implementing practical devices, and to demonstrate the feasibility of the applicable devices. The approach encompassed six main areas: (1) analysis and simulation, (2) evaluation, (3) experimental validation of theory, (4) material exploration and development, (5) feasibility demonstrations, and (6) collaborative interactions with material growers and system designers. Accomplishments were made in the following areas: coherent transient continuous optical processing, spatial spectral holographic optical routing and processing, coherent transient header/data isolation, relationships between material properties and system bandwidth, chirped reference pulse techniques for coherent transient processors, compensation for the deleterious effects of homogeneous dephasing, true time delay regeneration and processing, enhanced output efficiencies, spatial spectral holographic frequency division multiplexing, and optical coherent transient signal simulation.
