The spectroscopic properties, structure and interconversions of optically active oxygen-
deficiency-related point defects in vitreous silica are reviewed. These defects, the E …

This review presents the state of the art of the study of germanium-related colour centres in
silica glass and silica-based fibres. Most attention is concentrated on the dominant colour …

Due to its unique properties, amorphous silicon dioxide (a-SiO2) or silica is a key material in
many technological fields, such as high-power laser systems, telecommunications, and fiber …

The optical properties of point defects are frequently the most important parameter in
applications of glassy silica. They are relatively easy to measure on standard …

In recent years, optical fibers have found extensive use in special environments, including
high-energy radiation scenarios like nuclear explosion diagnostics and reactor monitoring …

The information revolution of this century was brought about by photonics based on simple
and common materials, such as glasses and semiconductors. Although semiconductors will …

We present data concerning the dynamics of photoexcitation of defect centers in germanium‐
doped silica glass optical fibers and fiber preforms. It is shown that two‐photon absorption of …

Experiments show that the characteristic periodic damage pattern that results from the
optical fuse can be produced by purely thermal means by heating the fiber to temperatures …

SiO 2 films with Ge+ implantation at an energy of 60 keV and a dose of 1× 10 16 cm− 2,
followed by annealing at different temperature, exhibit a broad infrared photoluminescence …
