One is the reduction of coupling losses by 0.9 dB relative to butt coupling. The other is the achievement of single-mode guidance in the bismuth HF at 1550 nm, although the fiber can support more than one mode in the case of free-space coupling.

Low-melting bismuth-borate glass: Composition development

Webglass, these materials had been widely studied since then. In 2001, Fujimoto et al. [4] reported the NIR luminescence characteristics in bismuth-doped aluminosili-cate glass. They reported that 500-nm pumped light can produce a luminescence at 1000–1600 nm with the half-peak width (FWHM) of 200 nm and the lifetime of 630 µs at a peak of 1140 nm. WebJun 1, 2024 · The density of boron-bismuth glass is mainly determined by the compactness of its glass network structure and the molecular mass of its constituents. Since the molecular mass of Bi 2 O 3 is much greater than that of B 2 O 3 and ZnO, the influence of the content of Bi 2 O 3 on the glass density of the glass system is greater than the … chuck savage photography https://blame-me.org
