Over the last two decades, several thousand exoplanets have been identified, and their
study has become a high scientific priority. Direct imaging of nearby exoplanets and the …

The Multi-Core Integral-Field Unit (MCIFU) is a new diffraction-limited near-infrared integral-
field unit for exoplanet atmosphere characterization with extreme adaptive optics (xAO) …

The study of free-space quantum communications requires tools from quantum information
theory, optics, and turbulence theory. Here we combine these tools to bound the ultimate …

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

Establishing secure communication links at a global scale is a major potential application of
quantum information science but also extremely challenging for the underlying technology …

In this paper, the material removal characteristics and mechanism of submerged pulsating
air jet polishing (SPAJP) process are investigated by polishing experiment on K9 glass and …

Photonic lanterns (PLs) are tapered waveguides that gradually transition from a multimode
fiber geometry to a bundle of single-mode fibers (SMFs). They can efficiently couple …

Studies of atmospheres of directly imaged extrasolar planets with high-resolution
spectrographs have shown that their characterization is predominantly limited by noise on …

The channel fading induced in the ocean quantum links is a major obstacle restricting the
performance of ocean quantum key distribution. To determine the ultimate limits at which …

Vortex fiber nulling (VFN) is a single-aperture interferometric technique for detecting and
characterizing exoplanets separated from their host star by less than a diffracted beam …
