The reported research explored non-traditional approaches to optical coherent transients applications and explored novel concepts designed to enhance optical coherent transient processing by exploiting the complex signal processing capabilities and non-linear behavior in optical coherent transient systems. The progress reported includes continuously programmed continuous processing optical coherent transient processor proposed and demonstrated high efficiency echoes greater than 100 demonstrated the theory and demonstration of the energy source of echoes study of virtual echoes via a six wave mixing processes BPSK and QPSK correlation demonstrating processing of multi-phase encoded information with optical-coherent transient nutational echoes investigated and demonstrated new methods for multi-GHz pulse shaping and arbitrary waveform generation using optical coherent transients are proposed and proof-of-concept demonstration was performed. methods for obtaining high efficiency 58 true-time-delay echoes using linear chirped programming are proposed and optical control of geometric phase in an optical coherent transient system is experimentally demonstrated.
