PIMMS: photonic integrated multimode microspectrograph
Joss Bland-Hawthorn,Jon Lawrence,Gordon Robertson,Sam Campbell,Ben Pope,Christopher H. Betters,Sergio G. Leon-Saval,Tim A. Birks,Roger Haynes,Nick Cvetojevic,Nem Jovanovic +10 more
TL;DR: Bland-Hawthorn et al. as mentioned in this paper presented the first integrated multimode photonic spectrograph, a device they call PIMMS #1, which comprises a set of multimode fibres that convert to single-mode propagation using a matching set of photonic lanterns.
Journal ArticleDOI

Wittenmyer +35 more
TL;DR: In this article, the authors present the data reduction procedures being used by the GALactic Archeology with Hermes (GALAH) survey, carried out with the HERMES fiber-fed, multi-object spectrograph on the 3.9m Anglo-Australian Telescope.
Journal ArticleDOI
First starlight spectrum captured using an integrated photonic micro-spectrograph
Nick Cvetojevic,Nick Cvetojevic,Nemanja Jovanovic,Nemanja Jovanovic,Christopher H. Betters,Jon Lawrence,Jon Lawrence,Simon Ellis,Gordon Robertson,Joss Bland-Hawthorn +9 more
TL;DR: In this article, the authors present results from the first on-telescope demonstration of a miniature photonic spectrograph for astronomy, by obtaining spectra spanning the entire H-band from several stellar targets.

Journal ArticleDOI
Beating the classical limit: A diffraction-limited spectrograph for an arbitrary input beam
TL;DR: A new approach to classical fiber-fed spectroscopy using a photonic lantern that converts an arbitrary input beam into N diffraction-limited outputs that is a first step towards a fully integrated, multimode photonic microspectrograph.
