 GeertMorthier
Geert Morthier received the degree in electrical engineering and the Ph.D. degree from the University of Gent in 1987, 1991, respectively. In 2001 he was appointed parttime professor at Ghent University.
Since 1991 he is a member of the permanent staff of IMEC. His main interests are in the modelling and characterisation of optoelectronic components. He has authored or co-authored around 100 papers in the field. He is also one of the two authors of the Handbook of Distributed Feedback Laser (Artech House, 1997) and co-editor of the book ‘How to model and measure photonic components: experience from a European project’ (Springer-Verlag, 1998). He has been the project manager of the ACTS project ACTUAL dealing with the control of widely tunable laser diodes and of the FP5 IST project NEWTON on new widely tunable lasers. He is currently the project manager of the FP7 ICT project HISTORIC on all optical logic and routing based on heterogeneous InP on silicon technology.
