Dr. Stefan Abel is Co-founder and Co-CEO of Lumiphase AG and driving the development and commercialization of Lumiphase’s innovative Pockels switching technology. Previously, Stefan spent more than 10 years at IBM where he invented new optical phase shifters based on ultra-efficient electro-optical materials integrated with standard silicon photonic products. At IBM, he was leading the R&D activities and client interactions on Pockels modulators and developed multiple new applications in the fields of optical communication, novel photonic computing, and sensing with light.
Controlling light with electrical signals is a critical function in photonic integrated circuits for optical communication, sensors, and switches. Lumiphase develops and manufactures photonic chips based on a unique BTO Pockels technology. The superior materials performances translate into electro-optical modulation functionalities with benefits in cost, speed, transparency, power-consumption, and footprint compared to standard silicon solutions. The Pockels-enhanced chips enable next-generation transceivers, both for coherent as well as direct-detect data transmission schemes, as well as for a wide range of photonic applications ranging such as sensing, data processing, or switching, where large numbers of ultra-efficient, integrated phase shifters are needed.
