Special Issue Information

Dear Colleagues,

Glass has for decades been a key material, suitable for the creation of a diverse range of passive and active devices, especially for photonics applications, and it has become of great interest for a wide range of applications related to telecommunications, light detection and ranging (LIDAR), solar panels, and spectroscopy, just to cite a few. Research has been focused on the development of new optical glass materials with new functionalities.

As optical (including the luminescence) properties are mainly determined by the glass composition, effort has been focused worldwide on the development of novel glass compositions. Since their discovery in 1953, glass ceramics have also become of particular focus. These materials are produced by controlled crystallization of glasses and therefore contain one or more crystalline phases evenly distributed within the glass phase. Controlled ceramization yields an array of materials with interesting combinations of properties, especially with enhanced optical properties (such as absorption and emission cross-sections and energy transfer rates) compared to their glassy counterparts if the crystalline phase of the desired nature and structure precipitates around the rare-earth ions.

The aim of this Special Issue is to highlight the latest developments in optical (active and passive) glasses and glass ceramics, and especially to advance the fundamental understanding of the relationship between material chemistry (both composition and structure) and optical, luminescence properties. Topics of interest also include the latest research on advanced characterization of material properties, new processing methods for the fabrication of glasses and glass ceramics, and advances in glass fibers and films.

Abstract
In the optical energy gap, visible and near-IR emission of halide phosphate glasses with a composition of 40P2O5-30ZnO-20LiCl-10BaF2 in mol% doped with 3.5 × 104 ppm Pr2O3, referred to as PZLBPr, were synthesized. [...] Read more.
In the optical energy gap, visible and near-IR emission of halide phosphate glasses with a composition of 40P2O5-30ZnO-20LiCl-10BaF2 in mol% doped with 3.5 × 104 ppm Pr2O3, referred to as PZLBPr, were synthesized. The UV-VIS-NIR and spectroscopic properties of these glasses were also predicted. The current glasses had broadband emission photoluminescence covering a wavelength range of 1250 to 1700 nm when excited at 455 nm. These bands for near-infrared emission luminescence relate to the transitions 1G4 → 3H5, 1D2 → 1G4, and 3H4 → 3F3, 3F4 in the optical telecommunication window. The significant PL emission wideband was caused by the radiative transition from Pr3+: 1D2 to 1G4. At 445 nm excitation, these glasses exhibited emission bands that corresponded to blue/reddish orange spectral ranges in visible ranges. The prepared glass has a high lasing quality factor (Ω4/Ω6 = 0.9), high optical energy (4.72 eV), and quantum efficiency = 87.3% with FWHM = 156 nm of transition emission from the 1D2 → 1G4 level. As a result, broadband near infrared optical amplifiers can be fabricated from the prepared glasses. Full article

Glasses in the TeO2-ZnO-Y2O3 (TZY) ternary system are examined in the present work. The vitrification domain of the chosen oxide matrix is determined and differential scanning calorimetry as well as X-ray diffraction measurements are carried out. The material characterizations reveal that Y2O3 incorporation cannot exceed 5 mol.% without causing detrimental crystallization within the glass. Optical transmission and refractive index investigations are conducted on compositions yielding fully amorphous samples. Next, the fiber drawing ability of selected yttrium-containing zinc-tellurite glasses is assessed and fiber-attenuation measurements in the mid-infrared are presented. Finally, a multimode step-index fiber is fabricated by combining a TZY cladding glass with a La2O3-based tellurite core glass. It is believed that yttrium-containing glasses could prove useful in association with other high glass transition temperature (>300 °C) TeO2-based materials for the design of robust optical fibers with precisely engineered refractive index profiles.

The influence of the addition of Y2O3 on the structural, spectroscopic, and laser properties of newly prepared Er, Yb-doped strontium-sodium phosphate glass was investigated. While the addition of Y2O3 has a small influence on the absorption spectra and fluorescence lifetime, it has a strong impact on the emission cross-section and on OH− content. The glasses were used as the active medium for diode-pumped laser emitting at 1556 nm. The increase in Y2O3 content leads to a significant 35% increase in laser slope efficiency up to 10.4%, but at the expense of the substantial reduction of the wavelength tunability from 82 to 54 nm.
