NAIR-APREXIS: Enabling photonics-based instruments for long-baseline interferometry and integral-field spectroscopy
L. Labadie, R. J. Harris, K. Madhav +14
The NAIR project -- Novel Astronomical Instrumentation based on photonic light Reformatting -- aims at advancing photonic technologies for infrared long-baseline interferometry and…
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…
All-fibre wavefront sensor
Thomas A. Wright, Stephanos Yerolatsitis, Kerrianne Harrington +2
We report on a tapered three-core optical fibre that can be used as a tip-tilt wavefront sensor. In this device, a coupled region of a few millimetres at the sensing tip of the fib…
Astrophotonics: astronomy and modern optics
S. Minardi, R. Harris, L. Labadie
Much of the progress in Astronomy has been driven by instrumental developments, from the first telescopes to fiber fed spectrographs. In this review we describe the field of astrop…
Modal noise mitigation for high-precision spectroscopy using a photonic reformatter
Fraser A. Pike, Aurélien Benoît, David G. MacLachlan +5
Recently, we demonstrated how an astrophotonic light reformatting device, based on a multicore fibre photonic lantern and a three-dimensional waveguide component, can be used to ef…
Simulation and Optimization of an Astrophotonic Reformatter
Th. Anagnos, R. J. Harris, M. K. Corrigan +7
Image slicing is a powerful technique in astronomy. It allows the instrument designer to reduce the slit width of the spectrograph, increasing spectral resolving power whilst retai…
A High Resolution Spectrograph for the 72 cm Waltz Telescope at Landessternwarte, Heidelberg
M. Tala, P. Heeren, M. Grill +14
The Waltz Spectrograph is a fiber-fed high-resolution échelle spectrograph for the 72 cm Waltz Telescope at the Landessternwarte, Heidelberg. It uses a 31.6 lines/mm 63.5…
Ultrafast Laser Inscription of a 121-Waveguide Fan-Out for Astrophotonics
R. R. Thomson, R. J. Harris, T. A. Birks +3
Using ultrafast laser inscription, we report the fabrication of a prototype three-dimensional 121-waveguide fan-out device capable of reformatting the output of a 120 core multicor…
