Multimode optical fibers have been primarily (and almost solely) used as “light pipes” in
short distance telecommunications and in remote and astronomical spectroscopy. The …

In no other field of astrophysics has the impact of new instrumentation been as substantial
as in the domain of exoplanets. Before 1995 our knowledge of exoplanets was mainly based …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

Insufficient instrument thermomechanical stability is one of the many roadblocks for
achieving 10 cm s− 1 Doppler radial velocity precision, the precision needed to detect Earth …

There are numerous advantages to exploiting diffraction-limited instrumentation at
astronomical observatories, which include smaller footprints, less mechanical and thermal …

We demonstrate for the first time an efficient, photonic-based astronomical spectrograph on
the 8-m Subaru Telescope. An extreme adaptive optics system is combined with pupil …

Recent advancements in photonic lantern design have stirred interest in computational tools
