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…
Development of integrated mode reformatting components for diffraction-limited spectroscopy
D. G. MacLachlan, R. J. Harris, D. Choudhury +5
We present the results of our work on developing fully integrated devices (photonic dicers) for reformatting multimode light to a diffraction limited pseudo-slit. These devices can…
Photonic spatial reformatting of stellar light for diffraction-limited spectroscopy
Robert J. Harris, David G. MacLachlan, Debaditya Choudhury +6
The spectral resolution of a dispersive spectrograph is dependent on the width of the entrance slit. This means that astronomical spectrographs trade-off throughput with spectral r…
End effects in optical fibres
Jeremy Allington-Smith, Colin Dunlop, Graham Murray +1
The performance of highly-multiplexed spectrographs is limited by focal degradation (FRD) in the optical fibres. It has already been shown that this is caused mainly by processes c…
Applications of Integrated Photonic Spectrographs in Astronomy
Robert James Harris, Jeremy Allington-Smith
One of the problems of producing instruments for Extremely Large Telescopes is that their size (and hence cost) scales rapidly with telescope aperture. To try to break this relatio…
