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

Optical beams and starlight distorted by atmospheric turbulence can be corrected with
adaptive optics systems to enable efficient coupling into single-mode fibers. Deformable …

We report on simulations carried out for an integrated phase corrector that can efficiently
couple the light distorted by atmospheric turbulence into a single-mode fiber (SMF). The …

The impact photonic technologies have had, and continue to have, on astronomical
interferometry are considerable and wide-ranging. Microscopic waveguide structures that …

Many modern astronomical instruments rely on the optimal coupling of starlight into single-
mode fibers (SMFs). For ground-based telescopes, this coupling is limited by atmospheric …

Existing AO systems generally measure the wavefront error at the pupil plane, using
wavefront sensors (WFSs) such as a Shack-Hartmann or pyramid sensor [2]. These sensors …
