Dynamic Organic Holograms
Dynamic holographic materials are a key component in optical processing systems,but existing materials such as photorefractive crystals are expenses
and of limited size, so we are investigating alternative reversible
photochemical affects in dye molecules suspended in polymer hosts that
promise to be cheap and efficient dynamic holograms.
We have developed and demonstrated dynamic photoanisotropic volume holograms
for applications such as incoherent-to-coherent optical converters and
joint transform correlators with performance superior to alternative
technologies, and analyzed the polarization dependent
anisotropic saturation responsible for holographic recording.
This is the first fully self-consistent coupled mode analysis of these
dynamic photoanisotropic materials that includes nonlinear response and
orientational anisotropies, and this model has been verified experimentally.
