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…
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…
Efficient photonic reformatting of celestial light for diffraction-limited spectroscopy
David G. MacLachlan, Robert J. Harris, Itandehui Gris-Sánchez +9
The spectral resolution of a dispersive astronomical spectrograph is limited by the trade-off between throughput and the width of the entrance slit. Photonic guided-wave transition…
Integrated photonic building blocks for next-generation astronomical instrumentation II: the multimode to single mode transition
Izabela Spaleniak, Nemanja Jovanovic, Simon Gross +3
There are numerous advantages to exploiting diffraction-limited instrumentation at astronomical observatories, which include smaller footprints, less mechanical and thermal instabi…
Multiband processing of multimode light: combining 3D photonic lanterns with waveguide Bragg gratings
Izabela Spaleniak, Simon Gross, Nemanja Jovanovic +4
The first demonstration of narrowband spectral filtering of multimode light on a 3D integrated photonic chip using photonic lanterns and waveguide Bragg gratings is reported. The p…
Integrated photonic building blocks for next-generation astronomical instrumentation I: the multimode waveguide
Nemanja Jovanovic, Izabela Spaleniak, Simon Gross +5
We report on the fabrication and characterization of composite multimode waveguide structures that consist of a stack of single-mode waveguides fabricated by ultrafast laser inscri…
High-precision photometry of WASP-12 b transits
G. Maciejewski, R. Errmann, St. Raetz +3
The transiting extrasolar planet WASP-12 b was found to be one of the most intensely irradiated exoplanets. It is unexpectedly bloated and is losing mass that may accrete into the…
Towards the Rosetta Stone of planet formation
G. Maciejewski, R. Neuhaeuser, R. Errmann +18
Transiting exoplanets (TEPs) observed just about 10 Myrs after formation of their host systems may serve as the Rosetta Stone for planet formation theories. They would give strong…
