More Information
Spectral-spatial holography
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.
