Design and simulation of a photonic lantern-inspired astrophotonic chip for spectral sensing
Avi Patel, Kevin A. Bundy, Aditya Sengupta +10
Compact astrophotonic sensors can trade general-purpose spectral coverage for task-specific wavelength discrimination in a small integrated footprint. Developed with the Mazin Lab…
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…
PEEPSS: Photonic-Enabled ExoPlanet Spectroscopic Sensor for the Habitable Worlds Observatory
Genevieve Markees, Stephen S. Eikenberry, Rodrigo Amezcua-Correa +5
The next few years will be critical for technology development for Habitable Worlds Observatory (HWO) in its mission to search for and characterize extrasolar planets. To achieve i…
On-sky demonstration of second-stage wavefront control with a photonic lantern
Aditya R. Sengupta, Jordan Diaz, Matthew DeMartino +14
Ground-based direct imaging of exoplanets at high contrast requires precise correction of atmospheric turbulence using adaptive optics (AO). The planet-to-star contrast ratio at sm…
The Santa Cruz Extreme AO Lab (SEAL) 2.0: A reflective, multi-wavelength rebuild
Rebecca Jensen-Clem, Vincent Chambouleyron, Prince Javier +20
The Santa cruz Extreme Adaptive optics Lab (SEAL) is a visible/near-infrared wavelength testbed designed to support technology development for high contrast imaging on large, segme…
Exploring the Capabilities of Astrophotonics for the Precise Alignment of Segmented Telescopes
Maria Cuevas, Aditya R. Sengupta, Vincent Chambouleyron +9
The next generation of large telescopes for direct imaging of exoplanets will require segmented primary mirrors. Over both long and short timescales, these telescopes experience se…
