Our cross-location competencies in Optoelectronic Systems

The technology platform »Optoelectronic Systems« focuses on the realization of optoelectronic devices and systems-on-chip. Applications include image acquisition and processing as well as communication up to Tbit/s-speed, Raman spectroscopy under strong scattered light conditions, and quantum optical sensors and measurement technologies for optical atomic clocks, for ground-based as well as space-based applications. From one single source, we offer the complete component and technology chain, e.g. for optical communication from emitter to modulator and receiver to fully integrated optoelectronic systems, including application-specific instruction-set processor based control and embedded software for these technologies.

Furthermore, the hybrid integration of active III-V-materials to polymer- and Si-based technology, incl. wafer level atomic layer deposition for encapsulation, plays a significant role in order to realize complete hybrid photonic integrated circuits (Hybrid PICs).
