Quantum-optimal coronagraphy with spatial mode sorting for direct exoplanet observations
Yinzi Xin, Sebastiaan Haffert, Yoo Jung Kim +1
Conventional coronagraphs struggle to reach the theoretical limit of exoplanet detection at close separations to the star, particularly when the telescope has a complex aperture or…

On-sky Demonstration of Subdiffraction-limited Astronomical Measurement Using a Photonic Lantern
Yoo Jung Kim, Michael P. Fitzgerald, Sébastien Vievard +18
Resolving fine details of astronomical objects provides critical insights into their underlying physical processes. This drives in part the desire to construct ever-larger telescop…

Implicit Electric Field Conjugation with the Photonic Lantern Nuller
Yinzi Xin, Daniel Echeverri, Nemanja Jovanovic +12
The Photonic Lantern Nuller (PLN) is an instrument concept designed to characterize exoplanets within a single beam-width from its host star. The PLN leverages the spatial symmetry…
