“…PIONIER relies on integrated optics (IO) technology to combine four beams (Malbet et al 1999;Berger et al 2001;Benisty et al 2009). In one observation, it provides the measurements of six visibilities and three independent closure phases with low spectral resolution (R ≈ 40) in the H band.…”

Context. PIONIER stands for PrecisionAims. In this paper, we explain the instrumental concept and describe the standard operational modes and the data reduction strategy. We present the typical performance and discuss how to improve them. Methods. This paper is based on laboratory data obtained during the integrations at IPAG, as well as on-sky data gathered during the commissioning at VLTI. We illustrate the imaging capability of PIONIER on the binaries δ Sco and HIP11231. Results. PIONIER provides six visibilities and three independent closure phases in the H band, either in a broadband mode or with a low spectral dispersion (R = 40), using natural light (i.e. unpolarized). The limiting magnitude is Hmag = 7 in dispersed mode under median atmospheric conditions (seeing <1 , τ 0 > 3 ms) with the 1.8 m Auxiliary Telescopes. We demonstrate a precision of 0.5 deg on the closure phases. The precision on the calibrated visibilities ranges from 3% to 15% depending on the atmospheric conditions. Conclusions. PIONIER was installed and successfully tested as a visitor instrument for the VLTI. It permits high angular resolution imaging studies at an unprecedented level of sensitivity. The successful combination of the four 8 m Unit Telescopes in March 2011 demonstrates that VLTI is ready for four-telescope operation.

“…Starting from available off-the-shelves components, we demonstrated the ability of the concept to meet the requirements of interferometry [27], [28]. From the first analysis, we have developed adapted components for astronomy, with suitable designs.…”

Abstract. Integrated optics (IO) is an optical technology that allows to reproduce optical circuits on a planar substrate. Since 1996, we have investigated the potentiality of IO in the framework of astronomical single mode interferometry. We review in this paper the principles of IO, the requirements for interferometry and the corresponding solutions offered by IO, the results of component characterization and the possible fields of application.Keywords: Interferometry, Optical aperture synthesis, Integrated Optics, Planar Optics, Single mode optics.Abstract. L'optique intégrée est une technologie qui permet de reproduire des circuits optiques sur un substrat planaire. Depuis 1996, nous menons des recherches sur les potentialités de l'optique intégrée dans le contexte de l'interférométrie monomode en astronomie. Dans cet article, nous passons en revue les principes de l'optique intégrée, les spécifications propresà l'interférométrie et les solutions correspondantes offertes par cette technologie, les résultats de caractérisations de composants ainsi que les domaines d'application.Mots clés : interférométrie, synthèse d'ouverture optique, optique intégrée, optique planaire, optique monomode.

“…Single-mode waveguides for astronomy are already available (Kern & Malbet 1996) in the visible and in the near infrared as single-mode fibres (Monerie et al 1985) or integrated optics devices (Malbet et al 1999). They should also soon be available in the thermal infrared range as fibres (Perrin et al 2000), hollow waveguides, or integrated optics waveguides.…”

Abstract. The DARWIN mission aims at directly detecting exoplanets, particularly telluric ones, around nearby stars and at performing a spectral analysis of their potential atmosphere. The major difficulty in achieving this goal is the huge luminosity contrast between the star and its possible planet(s). The mission concept is based on the star light rejection by nulling interferometry. This concept has never been experimentally demonstrated with high values of rejection (10 5 ) in the thermal infrared where DARWIN will observe. In this paper, we describe a laboratory test-bed that uses a CO2 laser at 10.6 µm to achieve this goal in a monochromatic case. We describe its principle, its sub-systems, their realizations and the first results we obtained with this interferometer.
