In the field of electronic-photonic broadband circuits, the research group explores novel systems that extend the state of the art in electronic or electronic-photonic systems through the use of photonic effects. In quantum research, the group makes significant contributions to the implementation and improvement of integrated quantum systems.

In addition to the foreseeable technological advancements in microelectronics, the technological maturity of photonic-integrated circuits has introduced a new dimension of promising improvements to the state of the art. The focus is therefore not only on research into transition components, such as integrated optical receivers with transimpedance amplifiers or integrated optical modulators with drivers, but also on the further development of classical electronic components like analog-to-digital converters or digital-to-analog converters using photonic components. Research is being conducted on electronic-photonic integrated circuits (ePICs), where photonic and electronic components share the same substrate, as well as on hybrid systems in which a purely electronic IC and a purely photonic IC are connected.

Another key research focus of the group is circuits for quantum systems. Ongoing research efforts concentrate on critical interfaces of photonic quantum systems, such as efficient fiber-to-chip or chip-to-chip couplings. Additionally, our group contributes its expertise in fast electronics, control systems, and driver circuits to this field of research.
