In this paper, we show a design example based on a couple of holographic gratings allowing the injection and the extraction of infrared light from a wave-guide. By means of suitable register conditions at 633 nm, we obtain a wave-guide when reconstructing in the infrared. In this way, we avoid the use of auxiliary tools, like a prism and index matching liquid, during the register process. We present some experimental results obtained under reconstruction beams at 980 nm.
