Silicon nitride photonic integrated circuits offer new possibilities for existing and emerging applications. Application such as Beamforming, Communication, Quantum, Microwave Photonics and Bio-sensing benefit from a transparency window from the visible to the Mid-Infrared, the ultra-low losses in those wavelength ranges and good power handling of cw and pulsed laser. LIGENTEC's fabrication process is based on the all-nitride-core technology and designed from the bottom up for photonics and modularity. In the all-nitride-core, most of the optical mode energy is in the waveguide material, which reduces loss and makes small bending radii possible. Latest developments on further integration of active elements and modules are presented.
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.
