Premiers développements de l'optique intégrée planaire monomode, pour les longueurs d'onde entre 2 et 20 micromètres, Applications à l'interférométrie stellaire

摘要

For many years, single-mode guided optics is used in stellar interferometry to ensure beam combination. The solution of planar integrated optics enables a high instrumental stability in a compact volume. Modal filtering associated to these advantages greatly increase the measurement precision of interferometric visibilities. Integrated optics offers decisives advantages for incoming space missions like Darwin and TPF "Terrestrial Planet Finder" working in the thermal infrared wavelengths [4-20 micrometers]. Silica based integrated optics technologies, developed in the near infrared spectral range, are implemented in the H atmospheric band [1470-1780 nm].
