Integrated optics in astronomical interferometry at IR wavelength is potentially very attractive compared to bulk optics in particular in the framework of thermal IR interferometric spatial missions aimed at the detection of terrestrial exoplanets like the IRSI/DARWIN mission. It would provide the spatial filtering function together with the beam combining functions inside a compact and stable device.
