Dielectric constant and loss tangent of polymer materials at microwave frequencies are important parameters for various industrial processes. Of particular interest is their temperature dependence. The developed setup allows to measure these properties up to the melting temperature.
The paper "Non-uniform longitudinal current density induced power saturation in GaAs-based high power diode lasers" by Seval Arslan et. al. was selected as featured article by the journal Applied Physics Letters.

Das FBH-Projekt BM=x³ – Attraktive berufliche Bildung in Mikro- und Nanotechnologie durch exzellente Berufe, exzellente Lernorte und exzellente Kooperationen wird im Livestream „Karliczek trifft die InnoVET-Projekte“ vorgestellt.
The event is co-hosted by the Centre for Quantum Technologies, NUS, and the QTX research forum – led by Alexander Ling of NUS and Markus Krutzik of Humboldt-Universität zu Berlin and Ferdinand-Braun-Institut, Leibnizinstitut für Höchstfrequenztechnik. The forum has previously met in Singapore (2018), Germany (2018) and UK (2019).
We have recently installed a hydrogen vacuum reflow solder system. Now, a more precise and stable positioning of components at high throughput is possible. Digitalization of process parameters additionally improves quality control.
The “GaN Microwave Devices Lab” is looking for an internship (Master/ Bachelor thesis) for optimizing Ohmic contacts for very high speed GaN-based transistors.
A charge-shifting CCD-SERDS approach using a custom 830 nm dual-wavelength diode laser and a specialized CCD overcomes technical limitations of conventional CCD operation. It reduces susceptibility to variations during the measurement and enables novel applications.
