Silicon photonics for electronic photonic integration

02.12.2019 von 16:00 bis 17:00


Already since the advent of cable telephony there is a remarkable growth of network traffic on a global scale. A similarity to Moore’s law of microelectronics has been pointed out. In fact, this permanent growth would have been impossible without the fascinating advance of IC technology.  The technologies required to sustain this unprecedented growth are photonic and electronic integration. Optical solutions intimately integrated with electronics are required to satisfy the demand of bandwidth, energy-per-bit, and cost. The power horse of electronic photonic integration is silicon photonics, in particular photonic CMOS or BiCMOS technologies. Going beyond the concept of present More-than-Moore technologies, photonic BiCMOS combines 2 high-performance technology sub-modules (high –performance HBTs and photonics) with a baseline CMOS process. The added complexity pays off with a full set of photonic features fit for broad-band optoelectronic system integration.

The talk shall provide a short introduction to the field of silicon photonics. We shall then present IHP’s perspective on a photonic More-than-Moore technology, joining most advanced HBT technology with high-speed photonic devices in photonic BiCMOS. The final part of the presentation will present examples of photonic electronic integration for a range of applications.



Lars Zimmermann leads the silicon photonics team at IHP, the Leibniz Institute für innovative Mikroelektronik in Frankfurt (Oder) and is professor at TU Berlin in the field of silicon photonics. He coordinates the cooperation of IHP and TU Berlin in the frame of the Joint Lab Silicon Photonics. His current work is dedicated to high-performance photonic-electronic integration for optical communications and for nonlinear optical signal processing. Lars Zimmermann undertook his postgraduate studies at Katholieke Universiteit Leuven, Belgium. In Leuven, he was affiliated with IMEC where he worked for 5 years and received a PhD degree in 2003. His scientific work at IMEC dealt with the development of extended short-wave infrared detector arrays and sensor assembly processes. In 2004, Lars Zimmermann moved to TU Berlin. In Berlin, he worked for 5 years on silicon-based optical motherboard technology, realizing early hybrid assemblies of silicon waveguides with lasers, semiconductor optical amplifiers, and detectors. In 2008, Lars Zimmermann moved to IHP, directing IHP’s silicon photonics developments. In 2018, he re-joined TU Berlin.
