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…
Analysis of Angular-Differential Post-Processing Algorithms for Exoplanet Direct Detection with a Photonic Lantern Nuller
Suvinay Goyal, Yinzi Xin, Nemanja Jovanovic +2
Exoplanet research is essential for understanding planetary formation and the potential for life beyond our solar system. The direct imaging method captures exoplanet light while m…
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…
