Spectral-Spatial Holographic Broadband Microwave Processing

Spatial-spectral holography combines the spatial storage and processing attributes of volume holography with spectral storage and processing attributes of persistent spectral holeburning. Spatial-spectral holographic (SSH) phenomenon encompasses optical coherent transients, photon echoes, and time-domain spectral holeburning. SSH materials have the ability to record the Fourier transforms of two temporally separated, modulated light beams in a spectral hologram analogous to the manner in which angled beams are recorded in spatial holograms. A SSH material is basically a fully programmable spectral-spatial filter with ultra-high spectral resolution and broad processing bandwidth whose impulse response is dictated by the programming pulses and their temporal shapes and their relative delay and direction. An appropriately programmed material processes incoming broadband optical beams by multiplying their Fourier decomposition by the material's programmed frequency response, resulting in a processed output temporal waveform. SSH materials thus offer an unmatched ability to store, process, and route complex broadband optical signals with precise phase and delay control.
