2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments

Monnier, John D.; Anugu, Narsireddy; Kraus, Stefan +77 more

Photonic technologies offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large Telescope in Chile that combines the light-gathering power of four 8 m telescopes through a complex photonic interferometer. Fully integrated astrophotonic …
