Photonics

Laser lab at the Photonics Institute

Photonics deals with creating and applying mainly coherent electromagnetic radiation in the visible and immediately adjacent spectral ranges. It has developed into a cutting-edge technology since the laser was invented. Established applications range from optical  communication, to high-performance material processing, to state-of-the-art medical applications, and chemical sensing. The photonics research field conducts basic research at the highest international level.

A major focus is the technical development of new photonic sources, mainly in the Terahertz, MIR, and XUV electromagnetic spectrum, along with their use in process technology, process engineering, and medicine. Based on existing highly developed femtosecond laser technology, application-specific, optimised high-performance laser systems along with new, laser-driven, coherent radiation sources are being developed for applications in XUV microscopy and lithography. Research activities include new optical technologies (super-resolution microscopy, adaptive optics) as well as the development of modern integrated, optical devices and circuits  (THz photonics), which constitute a foundation for future progress in communication technology, environmental monitoring , sensor technology, and biomedical applications.

The photonics field is undergoing rapid international growth, which is already reflected by the corresponding focus on the EU’s 7th framework programme. One of the reasons for the extraordinary scientific success of this primary field of research is that, in photonics, quantum effects can be directly implemented in technology. Two prominent examples are quantum cascade lasers and quantum information technology, both made possible through the mere combination of basic research findings with advances in materials science and nanotechnology. All our research and development work is supported by the Center for Micro and Nanostructures. This enables the realisation of new concepts by combining photonics with highly modern nanotechnologies – otherwise known as nanophotonics.

The photonics field’s high experimental competence is based on the laser laboratories for high-performance femtosecond technology and Terahertz technology. The Center for Micro and Nanostructures (ZMNS) forms the technological backbone for constructing and carrying out unique experiments in femtosecond laser technology and for fabricating  new optoelectronic and nanophotonic devices.
