Abstract
We present the experimental results of a 3D photonic component designed for the determination of coherence properties of astronomical targets in optical interferometry. The component is based on the properties of two dimensional arrays of evanescently coupled waveguides and has the potential of being scalable to arbitrary large arrays of telescopes. Simulations and rst experimental results will be presented together with perspectives for implementation of future instruments combining multiple telescopes.
