TC20 : Optoelectronics

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.

2018 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 also reported on the successful organization of PRE'17, the Seventh International Workshop on Photoluminescence in Rare Earths: Photonic Materials and Devices, held in Rome, Italy, from 29 November to 2 December 2017. The PRE Workshops constitute the flag event of TC20; like the previous editions, PRE17 was very successful, both for the technical content and for attendance: we had 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 (the formal approval by ICG CTC is still pending).

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

Aims and planned activities

TC20's Mission

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

TC20's research activities are very much concerned with materials for “Green Photonics”. In the next years the following topics are anticipated as of particular interest:

  • Glass Ceramic Phosphors 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 for Lighting and Solar Energy.  

2019 Planned Activities

A priority goal of TC20 members will be to effectively contribute to the 2019 events most relevant for this committee:

25th ICG Congress. The 25th International Congress on Glass will be held in Boston, Mass., June 9-14, 2019, hosted by ACerS Glass & Optical Materials Division. TC20 will organize the Session 10 of the Symposium IV (Emerging Applications of Glass) on Glass Materials and Devices for Photonic Systems. The abstract deadline is January 15, 2019. S. Jiang and G.C. Righini, who are coordinating this Session, are inviting glass scientists, technologists, and students to submit their contributions and to participate.     []

PRE'19. The 8th International Workshop on "Photoluminescence of Rare Earths: Photonic Materials and Devices" will be held in Nice (France) on 4-6 September 2019. The co-chairs are W. Blanc, P. Dorenbos, F. Vetrone. G. C. Righini is honorary chair, and  M. Ferrari is the TC20 representative in the Local Organizing Committee. []

Moreover, J. Ballato will organize the 6th Workshop on Specialty Optical Fibers and their applications. [] and K. Richardson is working to organize a Summer School in Photonics, to be held in conjunction with the ICG Congress.

Members of TC20 are also expected to actively participate in numerous conferences worldwide as chairs, program committee members, and invited lecturers.


Inter-TCs Collaboration: Following the contacts had with TC03 "Glass Structure" and TC28 “Glass fibres for reinforcement and insulation”, TC20 will aim at defining a joint plan to carry out common activities. 


Journals' Special Issues:  

The year 2019 will see the publication of some Special Issues on glass-related topics of international peer-reviewed journals, having some TC20 Committee members as Guest Editors. Besides the SIs already mentioned in the 2018 report, more SIs will be completed during 2019:

*** A Special Issue of the journal Optical Materials will be published, including selected, peer-reviewed, papers presented at the PRE'17 Workshop. The Guest Editors are Dominik Dorosz, Maurizio Ferrari, and Laeticia Petit. 

*** A Virtual Feature Issue of the open-access Optical Materials Express on Mid-Infrared Materials and their Device Applications will also be published. L. Petit is one of the Guest Editors, jointly with Juejun Hu, Luke Mawst, Steven Moss, and David Ting. On-line publication is in progress []



As mentioned above, in the 2018 Report, a 2019 activity will consist in the collection of reprints of articles published by TC20 members in open access international journals, with the goal of making 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



TC20 members are regularly contributing to the most important journals in the areas of glasses and optical - photonic materials. Invited contributions to glass books are also frequent, and sometimes books on different aspects of glass science and technology are authored or edited by TC20 members.
