Photonic lanterns are made by adiabatically merging several single-mode cores into one
multimode core. They provide low-loss interfaces between single-mode and multimode …

Since the discovery that tightly focused femtosecond laser pulses can induce a highly
localised and permanent refractive index modification in a large number of transparent …

Exploiting a particular wave property for a particular application necessitates components
capable of discriminating in the basis of that property. While spectral or polarisation …

Free-space optical communications are poised to alleviate the data-flow bottleneck
experienced by spacecraft as traditional radio frequencies reach their practical limit. While …

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

Abstract The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a
multipurpose high-contrast imaging platform designed for the discovery and detailed …

Forthcoming capacity scaling requirements of optical networks and advances in optical fiber
communications beyond the omnipresent single-mode fiber operating over the conventional …

Adaptive optics (AO) is critical in astronomy, optical communications and remote sensing to
deal with the rapid blurring caused by the Earth's turbulent atmosphere. But current AO …

Photonic technologies offer numerous advantages for astronomical instruments such as
spectrographs and interferometers owing to their small footprints and diverse range of …

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 …
