Machine-learning approach for optimal self-calibration and fringe tracking in photonic nulling interferometry

Barnaby R. M. Norris, Marc-Antoine Martinod, Peter Tuthill, Simon Gross et autres

Photonic technologies have enabled a generation of nulling interferometers, such as the guided light interferometric nulling technology instrument, potentially capable of imaging exoplanets and circumstellar structure at extreme contrast ratios by suppressing contaminating starlight, and paving the way to the characterization of …

Pyxis: a ground-based demonstrator for formation-flying optical interferometry

Jonah T. Hansen, Samuel Wade, Michael Ireland, Tony D. Travouillon et autres

In the past few years, there has been a resurgence in studies of space-based optical/infrared interferometry, particularly with the vision to use the technique to discover and characterize temperate Earth-like exoplanets around solar analogs. One of the key technological leaps needed to …

High-angular resolution and high contrast observations from Y to L band at the Very Large Telescope Interferometer with the Asgard Instrumental suite

Marc-Antoine Martinod, Denis Defrère, Michael Ireland, Stefan Kraus et autres

European Southern Observatory (ESO)’s Very Large Telescope Interferometer (VLTI), Paranal, Chile, is one of the most proficient observatories in the world for high angular resolution astronomy. It has hosted several interferometric instruments operating in various bandwidths in the infrared. As a result, …

The Pyxis Interferometer (I): scientific context, metrology system and optical design

Jonah T. Hansen, Michael Ireland, Tony D. Travouillon, Samuel Wade et autres

Optical interferometry from space is arguably the most exciting prospect for high angular resolution astrophysics; including the analysis of exoplanet atmospheres. This was highlighted in the recent ESA Voyage 2050 plan, which pointed out the exciting potential of this technology, but also …

Achromatic nulling interferometry and fringe tracking with 3D-photonic tricouplers with GLINT

Marc-Antoine Martinod, Teresa Deyi Maria Klinner-teo, Peter Tuthill, Simon Gross et autres

Nulling interferometry is one of the most promising techniques for imaging exoplanets at solar system scales as it simultaneously meets the stringent requirements for contrast and angular resolution. The GLINT instrument, operating at Subaru telescope behind the SCExAO extreme adaptive optics system, …

Interferometric beam combination with a triangular tricoupler photonic chip

Jonah T. Hansen, Michael Ireland, Andrew Ross‐Adams, Simon Gross et autres

Beam combiners are important components of an optical/infrared astrophysical interferometer, with many variants as to how to optimally combine two or more beams of light to fringe-track and obtain the complex fringe visibility. One such method is the use of an integrated …

Very high resolution spectro-interferometry with wavefront sensing capabilities on Subaru/SCExAO using photonics

Sébastien Vievard, Kyohoon Ahn, Alexander Arriola, Kévin Barjot et autres

Post Extreme Adaptive-Optics (ExAO) spectro-interferometers design allows high contrast imaging with an inner working angle down to half the theoretical angular resolution of the telescope. This regime, out of reach for conventional ExAO imaging systems, is obtained thanks to the interferometric recombination …
