The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) is an application-oriented research institute in the fields of high-frequency electronics, photonics and quantum physics. It researches electronic and optical components, modules and systems based on compound semiconductors. These devices are key enablers that address the needs of today’s society in fields like communications, energy, health, and mobility. It covers the entire value chain from design to ready-for-delivery systems.
At our Joint Lab for Integrated Quantum Sensors, we develop miniaturized and robust quantum sensors for applications outside the lab – ranging from mobile measurement heads to space-qualified platforms.
For a new research project focusing on the development of a compact optical atomic clock based on thermal strontium atoms, we are looking for a scientific employee to develop, assemble, and qualify micro-integrated optical systems.
