volume 1



Disseminating information on glasses designed and synthesized for application in the field of optics and photonics is part of the mission of TC20, one of the 28 Technical Committees of the International Commission on Glass (ICG). The purpose of a virtual collection of scientific papers (the present volume being only the first one) is to make easily accessible a set of publications which might not be available to the average reader otherwise.

This collection aims to be a store of knowledge on the special glasses that are fundamental for the development of many photonic devices, from optical fibers to integrated optical circuits, to lasers, optical amplifiers, white and colored light sources, scintillators, optical sensors, and so on. Fundamental physical and chemical properties, as well as advanced characterization techniques, are also treated in some of these papers.

The present volume includes some 20 papers, that represent a very small fraction of the very many articles and reviews published in international peer-reviewed journals by the academic and industrial researchers who are or have been members of TC20. Only papers published in Open Access format were selected, to avoid any problem related to a possible infringement of copyright. Moreover, in order to provide the reader an updated overview of this sector, the choice was limited to papers published from 2015 to 2018.

For sake of simplicity and as an aid to the reader, these papers are grouped in 6 sections, listed in alphabetical order, even if several of them could not be classified under a single label; as an example, an article focused on photoluminescence properties of a glass often contains useful information on the glass synthesis, too.

It is hoped that this collection could constitute a useful tool for the scientists in the field and at the same time an introduction for the newcomers to the outstanding properties of glass materials and of their applications in the area of optic and photonics.

The support by the ICG Coordinating Technical Committee (CTC) and the full collaboration of all the members of TC20 are gratefully acknowledged.
