2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Asgard/NOTT: L-band nulling interferometry at the VLTI I. Simulating the expected high-contrast performance
Romain Laugier, Denis Defrère, Benjamin Courtney-Barrer +13
Context: NOTT (formerly Hi-5) is a new high-contrast L' band (3.5-4.0 \textmu m) beam combiner for the VLTI with the ambitious goal to be sensitive to young giant exoplanets down t…
Achromatic design of a photonic tricoupler and phase shifter for broadband nulling interferometry
Teresa Klinner-Teo, Marc-Antoine Martinod, Peter Tuthill +3
Nulling interferometry is one of the most promising technologies for imaging exoplanets within stellar habitable zones. The use of photonics for carrying out nulling interferometry…
L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans
Denis Defrère, Azzurra Bigioli, Colin Dandumont +34
Hi-5 is the L'-band (3.5-4.0 m) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast a…
Ultrafast laser inscribed waveguides in tailored fluoride glasses: An enabling technology for mid-infrared integrated photonics devices
T Toney Fernandez, B Johnston, S Gross +6
Zirconium fluoride (ZBLAN) glass, the standard material used in fiber-based mid-infrared photonics, has been re-designed to enable the fabrication of high index-contrast low-loss w…
Interferometric Beam Combination with a Triangular Tricoupler Photonic Chip
Jonah T. Hansen, Michael J. Ireland, Andrew Ross-Adams +4
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-…
