Optical holographic interconnects: categorization and potential efficient passive resonated holograms

We consider several aspects of holographic optical interconnects. First we outline the various categories of holographic interconnects. We then show that obtaining a large number of superimposed holographic interconnects, all of high efficiency, in one hologram is difficult with present materials. Resonant mirrors around the hologram are suggested as a solution. It is shown that, with four mirrors around a lossless hologram of low diffraction efficiency, it is possible to choose mirror reflectivities to provide 100% diffraction efficiency. Angular beam widths and a recommended configuration are also presented.
