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.
The Materials Technology Department is developing, among other things, laser diodes in the blue-violet spectral range (380 nm to 430 nm), which are used in applications such as sensing, optical projection, or quantum technologies.
Reference number 20/25
