The highly skilled Team of professionals and experts has more than 20 years of experience in MEMS and Fiber Optical Components. Sercalo optical MEMS technology is based on small sized mirrors produced at varying diameters that allow light to be commuted between fibers, attenuated, filtered, or steered at different angles. Sercalo designs are leading the market because of their reliability, long-term stability, and high performance over lifetime. Mature MEMS technology means absence of friction and sticking and therefore no fatigue and no wear out of the mirror function. Sercalo fiber optic components are qualified against the Telcordia 1221 standard to withstand extreme environments (mechanical shock, vibration, damp heat, and thermal cycle testing etc.) and are manufactured according to ISO 9001 requirements.



Holds a degree in Microtechnology from Ecole Polytechnique Fédérale in Lausanne. In 1994 he joined the group of Prof. de Rooij at the University of Neuchâtel where he earned his Ph.D. in 1997. In 1999 he founded Sercalo Microtechnology Ltd. with the goal of bringing MEMS developments from Academia to Industry. As Chief Executive Officer, Cornel Marxer is leading the Sercalo Site in Neuchâtel / Switzerland.


Holds a degree in Mechanical Engineering and a degree in Business Administration from the University of Innsbruck / Austria, where he also earned his Ph.D. in 1989. From 1987 – 1995 Donat worked for Hilti Inc. holding senior management positions in Liechtenstein, the US and throughout Asia. Since 1995 he is an independent entrepreneur in Liechtenstein. He also serves on the board of different public and private corporations in Liechtenstein and Switzerland. In 1999 he co-founded Sercalo with his brother Cornel. As Chief Financial Officer he is in charge of contractual and financial activities. He is leading the Sercalo site in Schaan / Liechtenstein.


Holds a degree in Mechanical Engineering, also earned a M.Sc. degree in Electrical Engineering from TU-Wien in 2003. Between degrees, Peter worked in various engineering positions in Austria and San José / USA. In 2003 he worked on the development of the “Projection Focused Ion Beam”, a novel lithography tool. In 2004 Peter joined Sercalo where he has developed a broad range of new MEMS components and assemblies for industrial, communication and aero-space applications. As Chief Technical Officer, he currently leads the Sercalo Research & Development Team in Neuchâtel.
