Propagation losses in PICs are very important to have energy efficient on chip routing and are especially crucial if already very few photons are there to start with. In this talk we will give an overview of LIGENTEC’s low loss PICs based on silicon nitride and application areas in telecom/datacom, LiDAR, Quantum and sensing. Reliability and uniformity are of critical importance and are addressed with statistical process control in our 100mm and 200mm wafer fabrication.
Michael Geiselmann (Managing Director) studied physics and engineering at University Stuttgart and Ecole Centrale Paris. After his PhD at ICFO in Barcelona in 2014 he joined the laboratory of Prof. Kippenberg at EPFL in Lausanne, where he advanced frequency comb generation on integrated silicon nitride chips towards applications and was involved in several international research projects. In 2016, he co-founded LIGENTEC and brought the company to the international stage of photonic integration.
