Quantum Nano-Optoelectronics
Prof. Dr. Frank Koppens
- Activities:
The quantum nano-optoelectronic group, led by Prof. Koppens, studies interactions between light and matter at extreme limits. Several unique and novel techniques are exploited to confine light to nano-meter lengths scales and study physical processes at ultra-fast timescales. For example, we use near-field imaging techniques for infrared and THz light, and exploit ultra-fast lasers at low temperatures.
Central in these studies are the rich variety of novel materials that are only one atom thick: graphene and 2d materials. These materials exhibit fascinating properties that we have just begun to discover. Also novel quantum and topological materials and their interactions with light at the nano-scale are being studied.
In addition to the new science and physics, the group develops new concepts for photo-detection, imaging systems, optical modulation, nano-scale light processing and switching, as well as flexible and wearable health and fitness devices. We aim to build prototypes of these disruptive technologies, in collaboration with industry. The group works closely with the Graphene Flagship program, the largest European initiative with 1 Billion Euro funding for ten years.
We are hiring: Positions at Master-thesis, PhD- and Postdoctoral level available, within the framework of Topological Nano-photonics (ERC Grant) and the Graphene Flagship.
