ICFO is a young research institution that aims to advance the very limits of knowledge in Photonics, namely the science and technology of harnessing Light. Light, especially laser light, is one of the major enabling technologies currently available to humankind. Our research thrusts target the global forefront of photonics, and aim to tackle important challenges faced by society at large. We focus on current and future problems in Health, Energy, Information, Safety, Security and caring for the Environment.
