2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics 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…
Towards a data-driven model of the sky from low Earth orbit as observed by the Hubble Space Telescope
Sarah E. Caddy, Lee R. Spitler, Simon C. Ellis
The sky observed by space telescopes in Low Earth Orbit (LEO) can be dominated by stray light from multiple sources including the Earth, Sun and Moon. This stray light presents a s…
Seeking celestial Positronium with an OH-suppressed diffraction-limited spectrograph
J. Gordon Robertson, Simon Ellis, Qingshan Yu +4
Celestially, Positronium (Ps), has only been observed through gamma-ray emission produced by its annihilation. However, in its triplet state, a Ps atom has a mean lifetime long eno…
Potential of commercial SiN MPW platforms for developing mid/high-resolution integrated photonic spectrographs for astronomy
Pradip Gatkine, Nemanja Jovanovic, Christopher Hopgood +6
Integrated photonic spectrographs offer an avenue to extreme miniaturization of astronomical instruments, which would greatly benefit extremely large telescopes and future space mi…
First demonstration of OH suppression in a high efficiency near-infrared spectrograph
S. C. Ellis, J. Bland-Hawthorn, J. S. Lawrence +21
Ground-based near-infrared astronomy is severely hampered by the forest of atmospheric emission lines resulting from the rovibrational decay of OH molecules in the upper atmosphere…
Astro2020: Astrophotonics White Paper
Pradip Gatkine, Sylvain Veilleux, John Mather +19
Astrophotonics is the application of versatile photonic technologies to channel, manipulate, and disperse guided light from one or more telescopes to achieve scientific objectives…
