The Photonic Lantern Nuller: from concept to laboratory and on-sky demonstrations
Yinzi Xin, Nemanja Jovanovic, Dimitri Mawet +18
This thesis work presents the conceptual design and experimental characterization of the Photonic Lantern Nuller instrument, which uses a multimode-to-single-mode demultiplexing wa…
Instrumental artifacts in photonic lantern spectroastrometry and their mitigation with PLred
Yoo Jung Kim, Michael P. Fitzgerald, Malena Bloom +10
Spectroastrometry is a powerful spectral-differential technique for probing angular scales below the resolution limit, but it is also well known to be susceptible to instrumental a…
FIRST-PL: Commissioning the first visible photonic lantern spectrograph for sub-diffraction-limit astronomy on Subaru/SCExAO
Sebastien Vievard, Elsa Huby, Sylvestre Lacour +18
FIRST-PL (Fibered Imager foR a Single Telescope - Photonic Lantern) is a newly commissioned visible-light instrument on Subaru/SCExAO achieving spectroscopy below the diffraction l…
Tricouplers for nulling interferometry with photonic integrated circuits
Anusha Pai Asnodkar, Nemanja Jovanovic, Harry-Dean Kenchington Goldsmith +7
Solar System analog gas giants and habitable-zone terrestrial planets are observationally elusive to conventional exoplanet detection and characterization techniques, i.e. transits…
Technologies and novel components for broadband splitting and coupling in pairwise and nulling interferometry
Harry-Dean Kenchington Goldsmith, Nemanja Jovanovic, Anusha Pai Asnodkar +9
Passive and active photonic components are central to the continued development of astronomical photonic integrated circuits (PICs), although achieving broadband achromatic perform…
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…
Experimentally-determined performance limits for joint imaging and wavefront sensing with a photonic lantern
Aditya R. Sengupta, Vincent Chambouleyron, Rebecca Jensen-Clem +16
The photonic lantern (PL) is a focal-plane wavefront sensor (WFS) that can be used for second-stage control of extreme adaptive optics (AO) systems. While the number of sensed mode…
Combining spectroscopy and wavefront control at deep contrast with photonic lanterns
Mona El Morsy, Olivier Guyon, Barnaby Norris +7
HWO aims to directly image objects orbiting Sun-like stars, using a 6-m telescope capable of high-contrast imaging () and spectroscopy to search for biosignatures in plan…
Tri-coupler geometries for achromatic nulling interferometry in the near-infrared
Harry-Dean Kenchington Goldsmith, Nemanja Jovanovic, Anusha Pai Asnodkar +4
Astrophotonics is central to the next generation of astronomical instrumentation, enabling compact photonic integrated circuits for both ground-based observatories and future space…
