“…The experimental lifetime of SPCY was retrieved by the triple exponential fit and is shown in figure 10. The lifetime of the singly doped Yb 3+ in a silicate-based matrix for yellow emission at 325 nm was estimated to be 45.763 ns, compared to the longest lifetime of 975 µs reported in the literature [89]. The measured lifetime of SPCY is significantly shorter and suitable for pulsed yellow laser applications.…”

The influence of various trivalent lanthanides was investigated in the silica phosphate multi-component glass matrix, synthesized by the sol-gel method. The prepared glasses were analyzed to explore the degree of bandwidth amplification for telecommunication systems, and the potentiality of lasing media and smart glass films. Alkaline earth metal ions of Ca2+ were effectuated as a glass modifier, mediating the formation of non-bridging oxygen with the glass formers, and imputing favorable structural attributes to the glasses for versatile applications. The bonding parameter derived from the average nephelauxetic ratio implies covalency around the rare earth ion sites in the Er3+ and Nd3+ doped systems, while the Sm3+ doped glass exhibits ionicity. In the silica-based glass matrix singly doped with Yb3+, the coexistence of Yb3+/ Yb2+ ions was evidenced. Transitions across 4f14 and 4f135d levels of Yb2+, with an experimental lifetime of 45.8 ns would provide prospective pulsed yellow lasers, for non-invasive therapeutics. Er3+ doped glass evinced a large bandwidth of 93.775 nm at 1477 nm and a high quantum efficiency of 97%, favorable for O+E+S-band telecommunication networks. The transition corresponding to 4G_(5/2)→6H_(7/2) of Sm3+ and 2G_(7/2)→4I_(9/2) of Nd3+ is suggestive that the respective doped glasses could be devised into solid-state red and green laser sources. Novel NIR emission at 1476 nm was also evidenced in the Sm3+ and Nd3+ doped systems. Prominent absorption at 280 nm and complete transparency in the visible region observed in the Ce3+ mono-doped system make it ideal for smart glasses as UVB and UVC shielding films.

“…However, this indicator is somehow misleading with respect to the glass surface devitrification of the BGG compositions 15 , 16 , 25 . Avoiding alkaline ions as well as adding lanthanide oxides, i.e., Y 2 O 3 , La 2 O 3 , Yb 2 O 3 , Gd 2 O 3 , etc., in BGG glass compositions has proven to be a very effective mean to enhance the resilience to surface devitrification 13 , 15 , 16 , 26 , 27 . Nonetheless, the addition of lanthanide elements also significantly increases both glass melt viscosity and casting temperature.…”

The development of efficient and compact photonic systems in support of mid-infrared integrated optics is currently facing several challenges. To date, most mid-infrared glass-based devices are employing fluoride or chalcogenide glasses (FCGs). Although the commercialization of FCGs-based optical devices has rapidly grown during the last decade, their development is rather cumbersome due to either poor crystallization and hygroscopicity resilience or poor mechanical-thermal properties of the FCGs. To overcome these issues, the parallel development of heavy-metal oxide optical fiber from the barium-germanium-gallium oxide vitreous system (BGG) has revealed a promising alternative. However, over 30 years of fiber fabrication optimization, the final missing step of drawing BGG fibers with acceptable losses for meters-long active and passive optical devices had not yet been reached. In this article, we first identify the three most important factors that prevent the fabrication of low-loss BGG fibers i.e., surface quality, volumic striae and glass thermal-darkening. Each of the three factors is then addressed in setting up a protocol enabling the fabrication of low-loss optical fibers from gallium-rich BGG glass compositions. Accordingly, to the best of our knowledge, we report the lowest losses ever measured in a BGG glass fiber i.e., down to 200 dB km−1 at 1350 nm.
