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…
Characterization and on-sky testing of photonic, AWG-based astronomical spectrographs
Jeronimo Calderon-Gomez, Frantz Martinache, Nick Cvetojevic +14
The paper presents the characterization of arrayed‑waveguide grating (AWG) photonic chips and their on‑sky testing with a high‑resolution near‑infrared spectrograph prototype, demo…
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…
Demonstrating the integration of a photonic lantern with an all-fiber-based nulling interferometer
Jordan Diaz, Rebecca Jensen-Clem, Philip M. Hinz +12
High-contrast imaging of Solar System scale exoplanets and protoplanets demands advancements in instrumentation to access deeper starlight suppression at smaller angular separation…
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…
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…
