Space-variant holographic optical elements in dichromated gelatin.
Spatially variant holographic optical elements in dichromated gelatin can implement many complicated interconnection patterns and networks in a straightforward manner. We demonstrate some prototype, high efficiency, point to point, off-axis interconnects for replay at the recording wavelength (514.5 nm). Design considerations and potential uses in the fields of optical computing and optical communications are examined. Finally, we suggest a modified approach which allows for on-axis operation and replay in the near infrared.
