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…
An innovative integral field unit upgrade with 3D-printed micro-lenses for the RHEA at Subaru
Theodoros Anagnos, Pascal Maier, Philipp Hottinger +26
In the new era of Extremely Large Telescopes (ELTs) currently under construction, challenging requirements drive spectrograph designs towards techniques that efficiently use a faci…
A Multi-Core Fibre Photonic Lantern Based Spectrograph for Raman Spectroscopy
Christopher H. Betters, Joss Bland-Hawthorn, Salah Sukkarieh +2
We report on the development of a compact (volume 100\:cm), multimode diffraction-limited Raman spectrograph and probe designed to be compact as possible. The spectro…
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…
Modal noise characterisation of a hybrid reformatter
Izabela Spaleniak, David G. MacLachlan, Itandehui Gris-Sánchez +6
This paper reports on the modal noise characterisation of a hybrid reformatter. The device consists of a multicore-fibre photonic lantern and an ultrafast laser-inscribed slit refo…
Multiplexed Single-Mode Wavelength-to-Time Mapping of Multimode Light
Harikumar K. Chandrasekharan, Frauke Izdebski, Itandehui Gris-Sánchez +8
We demonstrate that photonic lanterns based on tapered multicore fibres provide an efficient way to couple multimode states of light to a two-dimensional array of Single-Photon Ava…
The Photonic Lantern
T. A. Birks, I. Gris-Sánchez, S. Yerolatsitis +2
Photonic lanterns are made by adiabatically merging several single-mode cores into one multimode core. They provide low-loss interfaces between single-mode and multimode systems wh…
Characterizing the variation of propagation constants in multicore fibre
Peter J. Mosley, Itandehui Gris-Sanchez, James M. Stone +3
We demonstrate a numerical technique that can evaluate the core-to-core variations in propagation constant in multicore fibre. Using a Markov Chain Monte Carlo process, we replicat…
