Paper Abstract

We present results on the application of integrated optics to singlemode near infrared astronomical interferometry. We review the laboratory optical properties of a two-telescope beamcombiner made by ion exchange on glass substrate. We report simultaneous detection of white-light interferograms with photometric calibration on the same detector. These encouraging results lead us into the design and the development of IONIC: an Integrated Optics Near-infrared Interferometric Camera. Finally we briefly discuss future developments of integrated optics applied to near-infrared interferometry carried out at LAOG.
