The research focus "Optoelectronics and Photonics" focuses on the development and optimisation of optical systems for the fields of communication, sensor technology and quantum information technology. The focus here is on semiconductor photonics, optical signal processing and non-linear optics. A key role is played by the participation in the Institute for Photonic Quantum Systems (PhoQS), which is dedicated to the research and application of quantum optical technologies

The development of efficient and environmentally friendly energy technologies and systems is central to the research focus "Sustainable Energy Technology and Electromobility". The focus is on renewable energies, intelligent energy systems, power electronics and innovative concepts for electromobility. The research aims to develop and optimise sustainable solutions for energy generation, storage and use. New approaches for a climate-friendly energy supply and sustainable mobility concepts are created through interdisciplinary collaboration with partners from science and industry.

In the "Innovative Didactics" research focus area, the Institute of Electrical Engineering at Paderborn University is concerned with the development and research of innovative teaching and learning concepts for school and university education, with a focus on the use of digital teaching methods, the creation of interactive learning environments and practical teaching approaches, with the aim of optimally preparing students for the challenges of science and industry. Special attention is paid to the integration of modern technologies and the promotion of action- and problem-oriented methods, whereby the findings from these fields are also incorporated into the design of teaching at the institute and are reflected, for example, in the provision of innovative teaching and learning materials.
