Silica glass doped with rare-earth ions remains one of the most frequently used materials for
fiber lasers and amplifiers, owing to various advantages such as high thermal resistance …

Since its first creation, glass has always fascinated with its optical properties, its ability to let
light through without being invisible. One of the most spectacular achievements of optical …

We prepared multicomponent silicate glass, which contained components with different
glass-forming abilities, such as GeO 2, Al 2 O 3 and ZnO, or different concentrations of glass …

We investigate the influence of various optical fiber fabrication processes on the
fluorescence decay of RE ions commonly used in fiber lasers and amplifiers, ie Yb^ 3+, Tm …

We study the fluorescence lifetime of Thulium-doped silica fibers for efficient laser operation
in the 2 μm “eye-safe” wavelength range pumped by 0.79 μm radiation. A large set of optical …

The transparency of optical fibers is one of the most sought-after properties for this optical
waveguide, the paradigmatic example being fibers for long-haul telecommunications. This …

Optical fibers, long an enabling technology for telecommunications, are proving to play a
central role in a growing number of modern applications, starting from high speed broad …

Inorganic photochromic (PC) materials with high light intensity modulation capability have
great potential for applications in optical memory devices, optical switches, and fluorescent …

Er/Yb-doped glass-ceramics from the A 2 O-ZnO-SiO 2 system (A= Li, Na, K, Cs) were
prepared. The glass-ceramics contained different crystalline phases, including zinc oxide …

The doping of dielectric nanoparticles (NPs) into the cores of silica fibers doped with a rare
earth (RE) has proven to be an effective approach for controlling the spectroscopic …
