The Fraunhofer Heinrich Hertz Institute (HHI) is pushing the boundaries of photonic chip manufacturing, with indium phosphide (InP) at the heart of its high-speed data communication technologies. Dr. Kristijan Posilovic, Head of Technology and Infrastructure, highlighted the material’s importance for low-loss fibre optic communication during a recent visit by the Research Factory Microelectronics Germany (FMD).
InP enables efficient light emission at precise wavelengths, which is essential for photonic chips that power everything from high-speed fibre networks to semiconductor lasers for fusion research. Fraunhofer HHI is scaling production to 6-inch wafers, a step aimed at improving industrial usability while minimising structural defects in larger crystals.
