Abstract
An HOE demultiplexer has been fabricated on a new holographic film, at 633nm. Our previous effort used dichromated gelatin, and was tested in the visible. Experiment results are presented showing performance at wavelengths of between 820 and 860nm. The results give a focused spot size of 150um and a diffraction efficiency (uncorrected) of 40%. The HOE demultiplexer is a single element thin film device that both disperses and focuses the light.
