Direct ultrafast laser processing is nowadays considered the most flexible technique
allowing to generate complex 3D optical functions in bulk glasses. The fact that the built-in …

The mid-infrared wavelength regime 3.5–4.1 μm, known as the astronomical L'band is of
special interest for exoplanet hunting. Mid-IR compatible photonic technologies are an …

The structuring of mid-IR materials, such as chalcogenide glass (ChG), at the micro and
nano scales, is of high interest for the fabrication of photonic devices in general, and for …

The germanium antimony selenide (Ge-Sb-Se) film has emerged as an appealing infrared
material with good photosensitivity, large nonlinear coefficient and high transmittance in …

To understand the unique features of germanium sulfide (~ 60–70 at.% of S) glasses
modified with Ga or Sb, the chemical order in these materials is investigated using X-ray …

The performance of ab initio descriptors derived from density functional theory simulations is
systematically investigated in comparison to traditional compositional descriptors for the …

Photo-thermo-refractive (PTR) glass doped with rare-earth ions has attracted considerable
attention due to its excellent linear photosensitivity and laser performance. This study …

We investigate an observed lack of excitation symmetry of discrete diffraction patterns in
periodic arrays of waveguides written by ultrafast laser inscription (ULI) in gallium lanthanum …

Low-power visible light can lead to spectacular nonlinear effects in soft-matter systems. The
propagation of visible light through transparent solutions of certain polymers can experience …
