Professor Iván Mora Seró and researchers Eva María Barea and Sofía Masi from the Advanced Semiconductors Group of the Institute of Advanced Materials (INAM) at the Universitat Jaume I, as well as Professor Rosario Vidal, from the Green Research and Development Group also at INAM, are participating in the development of low-cost halide perovskite superradiant lasers with the aim of ushering in a new era in materials science and optoelectronics, due to their potential in fields such as photovoltaic energy, quantum technology or computing and 6G technology.

The project "Room-temperature super-radiant perovskite lasers" has obtained funding of five hundred thousand euros from the European Union, within the EIC Pathfinder programme of Horizon Europe, for the creation of emitters that act as topological lasers with photonic crystal properties (without additional cavities) to achieve high power and a very narrow linewidth, similar to that of single optical transitions. The aim is to obtain new phases of perovskite and lay the foundations for superradiant lasers.

Today, the most up-to-date coherent light sources are the latest generation of lasers, such as free electron gas lasers or solid-state semiconductor gain media stabilised in high-quality optical cavities. In the case of the latter, there is a limitation on linewidth as a result of vibrations due to thermal noise in the cavity mirrors, which limits their power.

The aim of SUPERLASER is to change the laser field by producing low-cost, solution-processable, efficient, ultra-narrow linewidth perovskite halide superradiant lasers. Therefore, they will be applied as gain media combined with energy-matched charge transport materials to fabricate the first electrically pumped perovskite lasers operating at room temperature, which would be the first electrically pumped lasers from cheap solution-processed materials.

The aim is to use them in applications such as quantum computing and synchronisation, precise timekeeping, the detection of gravitational waves and ground-state cooling, all of which require pure, ultra-coherent light. And that is why the consortium is made up of partners with extensive experience in the field of lasers, materials, synthesis, devices and artificial intelligence.

The work plan will be carried out over three years and includes research into ways of reducing electronic waste, dependence on critical raw materials (CRM) and hazardous chemicals. To achieve this, in line with the Pathfinder programme's objective of developing new environmentally friendly electronic materials, recycling and reuse protocols will be applied to ensure that the technology developed does not generate electronic waste.

Coordinated by the National Centre for Scientific Research ‘Demokritel’ in Greece, the consortium is made up of the following partners: the Interuniversity Microelectronics Centre (Belgium); the University of Nottingham (United Kingdom); the Universitat Jaume I in Castelló (Spain); the University of Linköping (Sweden); LinXole AB (Sweden); Ethniko Kai Kapodistriako Panepistimio Athinon (Greece); Eurice European Research and Project Office GMB (Germany) and the Federal Polytechnic School of Lausanne (Switzerland) as associates.

Iván Mora Seró is a researcher in the Department of Physics and the Institute of Advanced Materials. In 2022 he was awarded the Prize for Research Excellence by the Royal Spanish Society of Chemistry. He is one of the most cited researchers in his field, and the 290 articles he has published have received more than 35,000 citations. In 2017 he won the prestigious European Consolidator Grant from the European Research Council to develop his project No-LIMIT, with the aim of improving the efficiency of solar cells through the synergistic interaction of different materials to overcome the limitations of current photovoltaic conversion.
