Department of Applied Physics
Physics is not satisfied with simply revealing the secrets of the universe. The discipline plays a far bigger role in society, contributing to the economy and the environment via the applications that result from the discoveries it makes.
The Applied Physics Group (GAP) was set up in 1980 to facilitate the transition from fundamental physics to practical applications.
GAP’s interests are designed to be wide-ranging in order to boost opportunities for technology transfer.
GAP now consists of seven groups working in the following fields:
- Biophotonics – Prof. Jean-Pierre Wolf : Biophotonics develops new processes to monitor and sometimes even control biological and atmospheric systems. Target applications include identifying bacteria in the ambient air, measuring pollutants, detecting early cancers and monitoring lightning.
- Quantum technologies – Prof. Hugo Zbinden : Quantum communication using fibre optics; in particular quantum cryptography, which is thought to be tamperproof and is based on the properties of quantum physics; and developing tools for quantum optics as simple photon sources and detectors.
- Quantum correlations – Prof. Nicolas Brunner : The theory of quantum information, exploring the fundamental concepts of quantum physics (such as nonlocality) and quantum thermodynamics. In addition, developing applications for information processing and metrology.
- Nonlinearity and climate – Prof. Jérôme Kasparian : The Nonlinearity and Climate group focuses on various nonlinear physical systems and their analogies: Propagation of high-power lasers, oceanic rogue waves, ecosystems, or modelling of climate change.
- Quantum electronics – Prof. Alberto Morpurgo : The group’s work aims to study the electronic properties of new materials with the thickness of one (or a handful of) atomic layers. It also explores the possibility of using these materials to produce opto-electronic devices with new functionalities.
- Quantum Networks - Prof. Wolfgang Tittel : The group is developing interfaces between matter and photons - generally based on nanophotonic resonators - enabling quantum communications between several users as well as networked quantum computing.
- Nonlinear Imaging - Prof. Luigi Bonacina : Our research is focused on the development of nonlinear optical methods for increased speed, selectivity, and sensitivity in biomaging applications. For example, by combining new laser sources with nanotechnology.
