LIGENTEC is a Swiss based manufacturing partner, offering low loss SiN Photonic Integrated Circuits (PICs) for industries such as Quantum technologies, LiDAR, Communications, Space and Sensors. Due to its high confinement, the thick nitride waveguides and resonators have low bending losses and excel even in high power applications from the visible to the mid-IR. The main application areas for this advanced silicon photonics low loss technology include coherent telecommunication, LiDAR, metrology, supercontinuum generation, spectroscopy, sensing and microwave photonics. LIGENTEC’s All Nitride Core Technology platform is fully CMOS compatible, thus allowing us to offer ramping up to high volumes benefiting from the scale of the semiconductor industry.

The team at LIGENTEC has the knowledge and facilities for thick film silicon nitride fabrication. In TeraSlice, LIGENTEC will contribute primarily to the microresonator fabrication, with the ultimate goal of providing photonic chips to the project partners for frequency comb generation with fabricated microresonators.

Dr. Michael Geiselmann studied Physics and Engineering Sciences at the University of Stuttgart and the prestigious Ecole Centrale Paris in the T.I.M.E. (Top Industrial Manager for Europe) program. In his one-year diploma thesis at University of Stuttgart in collaboration with the Max Planck Institute for Solid State Research, he was trained on working in the clean room to fabricate nanostructures and studying their time dynamics with a femtosecond pump-probe setup. After a short stay as a scientific employee in Stuttgart he joined the Institute of Photonic Sciences (ICFO) in Barcelona to pursue his PhD. Apart from the scientific success during the PhD, he chose to participate in a workshop organised by the Business School ESADE. In the workshop, “From Science to Business”, he attended lectures and case studies on how to start a company stemming from a scientific idea. This included finance, marketing, strategy and intellectual properties lectures, from which he benefits in building a start-up. In April 2014, he obtained his PhD from the Polytechnic University of Catalunya (UPC) with highest distinctions and honours. In July 2014, he became a scientist in the group of Prof. Tobias Kippenberg where he contributed to obtaining a coherent broadband optical frequency comb with gigahertz linespacing. He was eager to push this development further to bring the silicon nitride platform to the market; and thereby became a director and co-founder of LIGENTEC in 2016.
