Abstract
We demonstrate a 4 X 4 holographic star coupler fabricated at He-Ne laser light in silver- halide gelatin. A new approach has been tested for reducing the required number of gratings. It requires a simple recording geometry and a 3D arrangement of the replay beams based on Bragg degeneracy. This element can operate in a large window of replay wavelengths by adjusting the Bragg angles. Experimental results are presented.
