  1. Future of Optical-infrared Interferometry in Europe


We report recent results on passive mid-infrared integrated optics from the project “Advanced Laser-writing for Stellar Interferometry” and shortly describe the perspectives of their hybridisation with active components for the benefit of the spectro-interferometry technique.


Infrared interferometry VLTI Integrated optics 



ALSI is funded by the German Ministry of Education and Research (BMBF) through contracts 05A14PK2 and 05A14SJA.

Near and mid-IR research activities on spectro-interferometers are funded by the Labex FOCUS and the Action Spécifique Haute Résolution Angulaire.

We thank the anonymous referee for his comments aiming at improving the quality of the paper.
