Prof. Frank Koppens is group leader at the Institute of Photonic Sciences (ICFO). The Quantum Nano-Optoelectronics Group, led by Prof. Koppens, is at the forefront of exploring the fundamental science and potential applications of heterostructures of stacked and twisted two-dimensional (2D) materials. The group integrates the realms of nanophotonics, 2D materials, topology, emerging phenomena, and strong light-matter interactions, creating a multidisciplinary approach in their research.

Koppens has received the ERC starting grant, the ERC consolidator grant, and five ERC proof-of-concept grants. Other awards include the Christiaan Hugyensprijs 2012, the national award for research in Spain, the IUPAP young scientist prize in optics, and the ACS photonics investigator award. Since 2018 Koppens is on the Clarivate list for highly cited researchers, in the physics category, and in 2022 he has been elected as fellow of the American Physical Society.

The group focusses on the exploration of a wide array of novel materials that are a mere atom thick, such as graphene and other 2D materials. By layering and twisting these materials, like building with atomic Lego, we can engineer entirely new material systems and properties. The group employs a variety of innovative techniques to study the nano-optoelectronic properties, utilizing imaging methods that operate with infrared and terahertz light. This includes pioneering low-temperature near-field imaging techniques, which allow us to examine the electronic response to light with unprecedented nanometer-scale spatial resolution. Beyond advancing scientific knowledge, the group is pioneering new quantum technologies, including single-photon detection and quantum molecular sensing. The goal is to develop prototypes of these groundbreaking technologies in collaboration with industry partners, paving the way for revolutionary applications in the field.
