Real-time experimental demonstrations of a photonic lantern wavefront sensor

Jonathan W. Lin, Michael P. Fitzgerald, Yinzi Xin +12

The direct imaging of an Earth-like exoplanet will require sub-nanometric wavefront control across large light-collecting apertures, to reject host starlight and detect the faint p…

Spectroastrometry and Imaging Science with Photonic Lanterns on Extremely Large Telescopes

Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +11

Photonic lanterns (PLs) are tapered waveguides that gradually transition from a multi-mode fiber geometry to a bundle of single-mode fibers. In astronomical applications, PLs can e…

Nonlinear wavefront reconstruction from a pyramid sensor using neural networks

Alison P. Wong, Barnaby R. M. Norris, Vincent Deo +7

The pyramid wavefront sensor (PyWFS) has become increasingly popular to use in adaptive optics (AO) systems due to its high sensitivity. The main drawback of the PyWFS is that it i…

The path to detecting extraterrestrial life with astrophotonics

Nemanja Jovanovic, Yinzi Xin, Michael P. Fitzgerald +20

Astrophysical research into exoplanets has delivered thousands of confirmed planets orbiting distant stars. These planets span a wide ranges of size and composition, with diversity…

Post-processing CHARIS integral field spectrograph data with PyKLIP

Minghan Chen, Jason J. Wang, Timothy D. Brandt +4

We present the pyKLIP-CHARIS post-processing pipeline, a Python library that reduces high contrast imaging data for the CHARIS integral field spectrograph used with the SCExAO proj…

Photonic spectro-interferometry with SCExAO/FIRST at the Subaru Telescope: towards H-alpha imaging of protoplanets

Sébastien Vievard, Manon Lallement, Elsa Huby +27

FIRST is a post Extreme Adaptive-Optics (ExAO) spectro-interferometer operating in the Visible (600-800 nm, R~400). Its exquisite angular resolution (a sensitivity analysis of on-s…
