Silicon Photonics

The research area Silicon Photonics focuses on the development of optical and electro-optical technologies based on Group IV elements such as silicon and germanium.

These can be used for applications in communications and sensor technology. Since silicon and germanium are limited in their electro-​optical properties, alternative paths are also being researched in close cooperation with partners, especially for the integration of modulators and light sources. The development of devices as well as the integration of modules within a SiGe BiCMOS baseline technology are the focus of current activities. The high complexity of SOI (Silicon on Insulator) technologies is a particular challenge here. The main long-term objective of these developments is to transfer them to the research service of the IHP. Research and development focus on merging IHP’s outstanding SiGe HBTs (heterobipolar transistors) with high-​performance photonics to enable design and implementation of optoelectronic system-​on-chip solutions with state-​of-the-art high-​frequency characteristics.
