Longfei Shen gains his PhD cum laude

Longfei Shen of the Department of Electrical Engineering has gained his PhD cum laude. He defended his PhD thesis, about a novel photonic integration platform, Thursday in the Auditorium building of the university.

Shen worked on developing technologies and devices for a novel photonic integration platform, which combines high performance photonic integrated circuits with silicon-based electronic ICs. His aim was to exploit the potential bandwidth achievable with this platform. He thereby focused on the application of this platform in ultra-fast photodetectors. His promotor is prof.dr.ir. Meint Smit, professor in Photonic Integration.


Shen (1988) obtained a bachelor’s degree in Electrical Engineering from Zhejiang University in Hangzhou, China. In 2010 he came to Europe for study and research opportunities, supported by the Erasmus Mundus Scholarship. In 2012 he obtained a master’s degree of science in Photonics from Royal Institute of Technology (KTH) in Stockholm.

In 2012 he started his PhD research within the Photonic Integration (PhI) group of Eindhoven University of Technology which resulted in his thesis titled ‘Ultrafast Photodetector on the InP-Membrane-on-Silicon Platform’. Starting from September 2016 he is employed at the PhI group and the newly established JePPIX Technology Center (JTC), working on the research and development of photonic integrated circuits for industrial applications.


PhD awards with the honor of ‘cum laude’ are relatively rare, and an average of five percent of all theses at TU/e are considered for this distinction. To be eligible the PhD work must be of exceptional quality, and must be performed with an exceptional level of autonomy.
