Efficient passive holographic optical interconnects using resonated holograms

Holograms show promise as optical interconnects both for electronic intra and interchip applications and for numerical optical computing. We are concerned with applications where it is desirable to store many interconnects in the same hologram while maintaining good diffraction efficiency. To deal with the problem of low-diffraction efficiencies present in holographic materials with many superimposed exposures, resonant mirrors are added to reflect the light back and forth through the hologram, thus increasing reconstruction efficiency. Up to 100% efficiency is possible in lossless multiexposure holograms.
