Learning the Lantern: Neural network applications to broadband photonic lantern modelling
David Sweeney, Barnaby R. M. Norris, Peter Tuthill +4
Photonic lanterns allow the decomposition of highly multimodal light into a simplified modal basis such as single-moded and/or few-moded. They are increasingly finding uses in astr…
Seeking celestial Positronium with an OH-suppressed diffraction-limited spectrograph
J. Gordon Robertson, Simon Ellis, Qingshan Yu +4
Celestially, Positronium (Ps), has only been observed through gamma-ray emission produced by its annihilation. However, in its triplet state, a Ps atom has a mean lifetime long eno…
3D-M3: High-spatial resolution spectroscopy with extreme AO and 3D printed micro-lenslets
Theodoros Anagnos, Mareike Trappen, Blaise C. Kuo Tiong +20
By combining IFS with ExAO we are now able to resolve objects close to the diffraction-limit of large telescopes, exploring new science cases. We introduce an IFU designed to coupl…
All-fiber photonic lantern multimode optical receiver with coherent adaptive optics beam combining
Bo Zhang, Jianfeng Sun, Chenzhe Lao +4
A multimode optical receiver for free space optical communications (FSOC) based on a photonic lantern and adaptive optics coherent beam combining (CBC) of the lantern's single-mode…
