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…
Efficient ultra-broadband low-resolution astrophotonic spectrographs
Pradip Gatkine, Greg Sercel, Nemanja Jovanovic +9
Broadband low-resolution near-infrared spectrographs in a compact form are crucial for ground- and space-based astronomy and other fields of sensing. Astronomical spectroscopy pose…
Thermal control of long delay lines in a high-resolution astrophotonic spectrograph
Gregory P. Sercel, Pradip R. Gatkine, Nemanja Jovanovic +4
High-resolution astronomical spectroscopy carried out with a photonic Fourier transform spectrograph (FTS) requires long asymmetrical optical delay lines that can be dynamically tu…
The path to detecting extraterrestrial life with astrophotonics
Nemanja Jovanovic, Yinzi Xin, Michael P. Fitzgerald +20
Astrophysical research into exoplanets has delivered thousands of confirmed planets orbiting distant stars. These planets span a wide ranges of size and composition, with diversity…
