We present an experimental implementation of a packaged free-space optical interconnection system by photorefractive correlation. The system consists of a phase code, a LiNbO3 crystal, two computergenerated-hologram Fourier-transform lenses, and a detector, all mounted on a glass substrate. We present experimental results with a prototype packaged system showing interconnections between 25 inputs and 25 outputs, and we discuss the possibility of applying this packaging technology to interconnections between larger arrays.
