dc.description.abstractThe direct laser writing (DLW) using femtosecond lasers allows for the inscription of 3D microstructures embedded inside optical materials. Based solely on the silver ions photochemistry, the DLW in silver-containing glasses enables to locally induce inside glasses a unique combination of optical properties. The physical modifications of the material encompass not only a refractive index change, but also new physical properties like fluorescence, second- and third-harmonic generations, and surface plasmon resonance. Numerous efforts are deployed to develop the DLW-assisted silver photochemistry in phosphate glasses. However, this glass family is suffering from its near-infrared optical cutoff as opposed to the silver-doped gallo-germanate glasses. With an extended mid-infrared (mid-IR) transmission, these glasses are synthesized via the melt-quenching technique. Depending on the glass composition, either a glass matrix-based single track (Type I) or a silver cluster-based double track (Type A) of refractive index change is produced. By enabling an order of magnitude smaller structures than with Type I, Type A modification is further expanded to embed, for the first time, periodic structures below the inter-track spacing. Demonstrated with a pitch down to 400 nm, these Type A–based periodic structures bring new insights through the fabrication of 3D diffractive gratings in mid-IR glasses.
