Optical communication technology has been advancing rapidly for several decades,
supporting our increasingly information-driven society and economy. Much of this progress …

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 …

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

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 …

We model and demonstrate a simple mode selective all-fiber coupler capable of exciting
specific higher order modes in two-and few-mode fibres with high efficiency and purity. The …

We used ultrafast laser inscription to fabricate three-dimensional integrated optical
transitions that efficiently couple light from a multimode waveguide to a two-dimensional …

The “photonic lantern,” an optical fibre device that has emerged from the field of
astrophotonics, allows for a single-mode photonic function to take place within a multimode …

We introduce optically clear and resilient free-form micro-optical components of pure (non-
photosensitized) organic-inorganic SZ2080 material made by femtosecond 3D laser …

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 …
