All-fibre wavefront sensor
Thomas A. Wright, Stephanos Yerolatsitis, Kerrianne Harrington +2
We report on a tapered three-core optical fibre that can be used as a tip-tilt wavefront sensor. In this device, a coupled region of a few millimetres at the sensing tip of the fib…
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…
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…
Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit
Sebastiaan Y. Haffert, Robert J. Harris, Alessio Zanutta +31
Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanets atmosphere, but most direc…
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…
Multicore fibre photonic lanterns for precision radial velocity science
Itandehui Gris-Sánchez, Dionne M. Haynes, Katjana Ehrlich +2
Envisioning more compact and cost accessible astronomical instruments is now possible with existing photonic technologies like specialty optical fibres, photonic lanterns and ultra…
