Inverse-designed tapers to improve throughput of on-chip astrophotonic spectrographs
Vikram Seenivasan, Pradip Gatkine
Astrophotonics offers a pathway towards compact and stable spectrographs for future large telescopes. The size of these spectrographs does not scale with the diameter of the telesc…
Simulation and development of astrophotonic H-band nulling beam combiner for the CHARA Array
Samantha G. Morrison, Pradip Gatkine, Michael P. Fitzgerald
Nulling interferometry is a promising method for direct detection and characterization of faint stellar companions such as exoplanets and faint binary sources. The dominant constra…
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
Astrophotonics is a field that intends to meet the needs of next-generation instruments at a small footprint, low cost, and high stability, compared to bulk-optics-based alternativ…
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…
