AstroPIC III: advancing the near-infrared photonic integrated coronagraph for the Habitable Worlds Observatory

AstroPIC is a photonic integrated coronagraph concept for the Habitable Worlds Observatory (HWO) that uses a programmable Mach-Zehnder interferometer mesh to perform coronagraphic mode-sorting of starlight while preserving off-axis exoplanet light. This paper presents a Gen-2 technology update and modeling study. The G...

Coronagraph design survey

NASA is embarking on an ambitious program to develop the Habitable Worlds Observatory (HWO) flagship to perform transformational astrophysics, as well as directly image ∼25 potentially Earth-like planets and spectroscopically characterize them for signs of life. This mission was recommended by the Astro2020 decadal sur...
