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.

Activities and plans

2016 Activity

The Committee meets at least once per year. The 2016 meeting was held in Kyoto, Japan, on November 14th, 2016, during the CerSJ-GOMD Joint Symposium on Glass Science and Technologies. The meeting was attended by John Ballato, Shibin Jiang, Yuki Kondo, Kathleen Richardson, Setsuhisa Tanabe; the ICG President, Manoj Choudhary, was a most welcome guest. The update of TC20 membership and the Committee activities, both ongoing and planned, were discussed there.

As to institutional activities, the TC20 chair, Giancarlo C. Righini, participated in the ICG CTC Meeting in Madrid, on 18-19 February, 2016; A. Jha and S. Jiang gave invited lectures at the ICG triennial Congress in Shanghai, on 7-11 April, 2016.

Here a summary of 2016 activities is presented:

a) International Year of Light - IYL2015 

Some TC20 members were deeply involved in the celebrations of the International Year of Light, that continued from the official opening ceremony of IYL2015 in Paris, France, on January 19-20, 2015, until the conclusive ceremony in Merida, Mexico, on 4-6 February 2016. G.C. Righini attended both the events.  IYL 2015 saw over 13,000 events take place with an impact that reached 147 countries; the final report may be downloaded from        

TC20 contributed to IYL2015 initiatives through the work of G.C. Righini and S. Tanabe, who, together with John Capobianco, were Guest Editors of a Special Issue on "Light, Energy and Life" of Journal of Luminescence, which appeared as Volume 170, Part 3 (2016). Authors of the published articles included several TC20 members.

S. Tanabe also published two review papers "Glass and Rare-Earth Elements: A Personal Perspectives" and "Glass Ceramics and Solid-State Lighting" in the Special Issue on "Glass and Light" of IJAGS (December 2015).

TC20 members also started to work on the preparation of a mobile “app” for tablets and smart phones about Glass and Light, aimed at explaining young people what glass is and how important it is in the everyday life, Due to some unexpected problems, the work is still in progress; it is considered, however, that the app would be useful for outreach independently on the closing of IYL2015.

b) Collaborative research projects

Several TC20 members actively participate in the European Action COST MP1401 “Advanced fibre laser and coherent source as tools for society, manufacturing and life science”. S. Taccheo is chair of the action, and L. Petit is Management Committee (MC) member; J.-L. Adam and D. Dorosz are MC substitutes.

Among industrial research projects, it can be noted that S. Jiang developed a laser for glass drilling and cutting.

c) Organization of international conferences 

The main TC20 activity in this area was the organization of PRE'16, the "flagship" workshop of the Committee; it was held in Greenville, South Carolina (USA) on 8 - 10 June, 2016. Conference chairs were Luiz G. Jacobsohn and John Ballato (Clemson University).   "PRE" is the acronym of the series of International Workshops on "Photoluminescence in Rare Earths", covering a wide range of research topics concerning the properties and applications of rare-earth ions in optoelectronics and photonics. The series begun in Trento, Italy in May 2005 (PRE’05), followed by PRE’07 again in Trento, PRE’10 in Firenze (Italy), PRE’12 in Kyoto (Japan), PRE’14 in San Sebastián (Spain). PRE Workshops aim at providing a forum for material scientists, chemists and physicists where to debate about the state of the art and the perspectives of the photonic materials based on rare earth ions. Both fundamental photoluminescence properties and application oriented material investigations are considered.

Members of TC20 also actively participated to many other conferences, such as (list is not exhaustive, and only the main activities are reported): 


13-18: SPIE Photonics West, San Francisco, USA. S. Jiang was symposium chair for OPTO (Optoelectronic Materials and Devices) and CC of “Optical Components and Materials XIII”; R.

Ballato co-chairs; 156 papers were presented and more than 320 people participated, including ICG President M. Choudhary and six TC20 members; Hirao, Ohishi and Richardson PC; S. Jiang IS).  Special Industry Session on "Glass Melting" was organized on Nov. 15th, where M. Choudhary, R. Conradt (ICG SteCo) and 5 more experts from US and Japanese industries presented 7 invited talks.

Aims and planned activities

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.  

2017 Activity

Committee Meetings:  Two meetings of the TC20 Committee are planned in 2017, the first one during the PACRIM12-GOMD2017 Conference in Hawaii, and the second one during PRE'17 in Rome. At the moment it is not clear if some TC20 members will be able to participate in the Annual ICG Meeting in Istanbul, Turkey, October 22-25, 2017. (

Other Activities: Main focus of the TC20 activity in 2017 will be the organization of PRE'17, which will be held in Rome, Italy, 30 November - 2 December 2017 [].  It will be the 7th edition of the International Workshops on Photoluminescence of Rare-Earth: Photonic Materials and Applications, begun in Trento, Italy, in 2005. The chairs of PRE'17 are D. Dorosz, M. Ferrari and L. Petit; G.C. Righini is honorary chair. The Enrico Fermi Center (Rome) and SIOF (the Italian Society of Optics and Photonics) will be the vent managers. A Special Issue of the journal Optical Materials will be published, that will include selected, peer-reviewed, papers presented at the Workshop.

S. Jiang and G.C. Righini are Guest Editors, together with F. Prudenzano (Polytechnic of Bari, Italy) of a Special Issue of the Journal Fibers on Advances in Optical Fibers (II). TC20 members arecontributing with invited papers. The S.I. should be completed by December 2017.
