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 …

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 …

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

Characterisation of exoplanets is key to understanding their formation, composition and
potential for life. Nulling interferometry, combined with extreme adaptive optics, is among the …

We present a novel method to fabricate low bend loss femtosecond-laser written
waveguides that exploits the differential thermal stabilities of laser induced refractive index …

The characterization of exoplanets is critical to understanding planet diversity and formation,
their atmospheric composition, and the potential for life. This endeavour is greatly enhanced …

Direct laser write of volume Bragg gratings with diffraction efficiency (absolute)∼ 90% is
demonstrated using Gauss-Bessel laser beams in fused silica glass. Axial multiplexing of∼ …

Ultrafast laser photoinscription of optical materials has seen a strong development in the
recent years for a range of applications in integrated photonics. Fueled by its capability to …

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 …

Astrophotonics is the application of photonic technologies to channel, manipulate, and
disperse light from one or more telescopes to achieve scientific objectives in astronomy in …
