The current frequent issue focuses on recent FBH developments based on wide-bandgap and ultra-widebandgap semiconductors - and their important role in reducing the energy consumption of modern systems and preserving resources.

We’ve developed a 780 nm distributed feedback laser which, by design, provides mode-hop free tuning over a wide range of currents and temperatures. It can serve as an enabling component for more complex systems such as sources for hybrid integrated photonic circuits.

Securing skilled workers for the chip industry – with this goal in mind, the nationwide flagship project “Skilled workers for microelectronics: skills4chips” funded by the Federal Ministry of Education and Research (BMBF), launches on November 1, 2024. A key component is the establishment of a national educational academy for microelectronics and microsystem technology. The “Microtec Academy” will address the growing demand for skilled workers with innovative training programs and is coordinated by the Berlin-based Ferdinand-Braun-Institut (FBH).

We developed a novel stripline-to-waveguide transition and a corrugated horn antenna, which are ideal for space applications due to their reduced size and weight. Both technologies are easily scalable and more cost-effective compared to conventional approaches.

Raman spectroscopy can determine the chemical composition of milk. We use an in-house developed 785 nm dual-wavelength diode laser and SERDS to successfully identify major milk ingredients and to determine the milk fat content within seconds.

Dr.-Ing. Thomas Flisgen has been appointed as Professor of Electromagnetic Field Theory at the Brandenburg University of Technology Cottbus-Senftenberg (BTU) starting in the winter semester of 2024/25. In this role, he will drive research and teaching in the field of electromagnetic field computation and further strengthen the strategic partnership between BTU and the Berlin-based Ferdinand-Braun-Institut (FBH).

We demonstrate a compact optical frequency reference using a novel 778.1 nm laser. Promising results indicate the feasibility of micro-integrating these references into matchbox-sized units for field and space applications.
