Achromatic photonic tricouplers for application in nulling interferometry
Marc-Antoine Martinod, Peter Tuthill, Simon Gross +3
Integrated-optic components are being increasingly used in astrophysics, mainly where accuracy and precision are paramount. One such emerging technology is nulling interferometry t…
Building hybridized 28-baseline pupil-remapping photonic interferometers for future high resolution imaging
Nick Cvetojevic, Barnaby R. M. Norris, Simon Gross +7
One key advantage of single-mode photonic technologies for interferometric use is their ability to easily scale to an ever increasing number of inputs without a major increase in t…
Photonics-based mid-infrared interferometry: 4-year results of the ALSI project and future prospects
L. Labadie, S. Minardi, J. Tepper +7
In this contribution, we review the results of the ALSI project (Advanced Laser-writing for Stellar Interferometry), aimed at assessing the potential of ultrafast laser writing to…
Modal noise in an integrated photonic lantern fed diffraction-limited spectrograph
N. Cvetojevic, N. Jovanovic, S. Gross +9
In an attempt to develop a streamlined astrophotonic instrument, we demonstrate the realization of an all-photonic device capable of both multimode to single mode conversion and sp…
High-performance 3D waveguide architecture for astronomical pupil-remapping interferometry
Barnaby Norris, Nick Cvetojevic, Simon Gross +6
The detection and characterisation of extra-solar planets is a major theme driving modern astronomy, with the vast majority of such measurements being achieved by Doppler radial-ve…
Integrated photonic building blocks for next-generation astronomical instrumentation II: the multimode to single mode transition
