TC20 : Photonic glasses and optical fibers

TC20 focuses on glasses finding their application in optoelectronics and photonics. All the aspects of research & development are considered, going from design and fundamental properties to characterization and applications. In the recent years much attention has been devoted to new materials (glasses and glass-ceramics) for Lighting and Solar Energy. TC20 promotes international collaborations and sponsors international Workshops and Conferences relevant to the field.

TC20 Mission

The main goal of TC20 is to keep monitoring the international trends in optoelectronic/photonic glasses and to contribute to the advances of scientific knowledge and information in this area. Outreach, addressed to students and general public, will be an important part of the Committee's activity. The global aim is to maintain the centrality of glass in the next generations’ photonic devices; particular attention is therefore devoted to advanced and novel materials, such as glass ceramics, hybrid glasses, nanostructured glasses, and to fundamental components, such as optical fibres and glass integrated optical circuits.

TC20's research activities are also very much concerned with materials for “Green Photonics”.

In the next years the following topics are anticipated as of particular interest:

Glass ceramic phosphors and new materials for Solid-State Lighting

Persistent phosphors

New glasses and fibers for fiber lasers and nonlinear optics

New materials and process for infrared imaging and sensing

Optical computing becoming more practical based on new materials

New materials and films for Solar Cells

Ultrathin glasses for Flexible Photonics.  

 

 

Following a request from the CTC (Coordinating Technical Committee) of ICG, a short video presenting the mission and main activities of TC20 was made available at the ICG2019 Congress in Boston. It is now available on YouTube, too.  https://youtu.be/G-3jRa1Q6Ws

 

 

2018/2019 Activity - a short report

The focus of 2018 activity was the ICG Annual Congress in Yokohama, Japan (23-26 September 2018), where Setsuhisa Tanabe and Giancarlo Righini organized a topical section on "Glasses for 21st century photonic technologies". Several TC20 members actively participated to the topical section, which saw, inside 6 parallel sessions during the three Congress days, a total of 33 oral presentations (11 invited).  A meeting of the TC20 Committee was also held during the ICG Congress in Yokohama, with a large participation (10 members were present).  It was agreed to devote more attention to outreach activities, also to illustrate the mission of ICG and TC20. To increase the knowledge of the properties and potentialities of the glasses for optoelectronics, it was also agreed to collect from TC20 members a few scientific articles already published in open access format, and to present them in the website. Such a “store of knowledge” could be useful to provide an updated overview of some recent advances in our research field. 

Among other issues, Righini reported on the successful organization of PRE'17  and on the progressing organization of PRE'19, to be held in Nice, France, 4-6 September 2019. The 7th International Workshop on Photoluminescence in Rare Earths: Photonic Materials and Devices (PRE'17) was held in Rome, Italy, in November 2017 (http://pre17.fbk.eu). There were 140 participants from 28 countries; the technical program included 2 plenary lectures, 14 invited lectures, 61 oral communications and 60 poster presentations. Several TC20 members attended the workshop and contributed to its high scientific level.  

Besides the usual business, the agenda of the TC20 meeting included the discussion of the possibility of common activities with TC03 "Glass Structure" and TC28 “Glass fibres for reinforcement and insulation”. Daniel Neuville (TC03, chair), Yuanzheng Yue (TC28, chair) and Hong Li (TC28, vice chair) attended the second part of the meeting; it was agreed that a couple of TC20 members (Ferrari, Nalin) could send samples and information to the TC03 and TC28 colleagues for further characterization and analysis. A photo of the participants in the Committee meeting is shown above.

A few Committee members had also met in Québec City [see a photo below]. during the 21st International Symposium on Non-Oxide and New Optical Glasses (ISNOG), 17-21 June 2018, where they were delivering invited talks and a keynote lecture (S. Tanabe).

At the end of 2018, TC20 received the applications of two new members, namely Dr. Xin Jiang, Max Planck Institute for the Science of Light, Erlangen, Germany and Prof. Yong Gyu Choi, Korea Aerospace University, Korea. After evaluation of their curricula, TC20 expressed full agreement and congratulated with the two new members.

During 2018, many other activities were carried out by TC20 members; in the following we mention some of them.

PHOTONIC GLASSES: A STORE OF KNOWLEDGE

An activity begun in 2018 and continuing in the next years consists in arranging a collection of reprints of articles published by TC20 members in open access international journals. The provisional name of such a collection is PHOTONIC GLASSES: A STORE OF KNOWLEDGE, and is edited by Giancarlo C. Righini. Its goal is to make easily available a virtual volume whose contents may be greatly useful to both the researchers and the newcomers to the field of glasses for optics and photonics.

A preliminary set of articles is available since mid December 2018 at the address www.ifac.cnr.it/~righini/TC20
