Abstract：
Silicon photonics has gained a lot of momentum both as a research discipline and as an industrially relevant technology.
In the first part of this talk I will give a broad introduction to the field, the main achievements in recent years and the main applications.
In the second part of the talk I will focus on hybrid silicon lasers, based on bonded III-V layers on top of a silicon waveguide circuit. A considerable number of concepts have been reported for such lasers, in particular with respect to the type of cavity, the type of light coupling between the silicon layer and the III-V layer and the degree of light confinement in the gain layer. While good performance has been demonstrated for various devices, it is also true to say that in most cases performance is far from ideal. Hence the question arises how to evolve to more ideal hybrid silicon lasers. I will review the most important hybrid silicon lasers reported so far with respect to these performance criteria and discuss possible options towards a more complete coverage of desired properties.
招生讲座：European Master of Science in Photonics

Abstract：
Since 2006 a prestigious European Master of Science program has been set up in the field of photonics. It aims to prepare excellent students for an academic or industrial career in photonics. The program is a joint English-taught program organized by Ghent University and University of Brussels in Belgium and University of St Andrews in the United Kingdom. Furthermore the Technical University of Denmark, Ecole Polytechnique Federale de Lausanne, the Polytechnic University of Valencia and National Taiwan University are associated to the program and welcome our students for a master thesis project.
The program is a two-year (four-semester) program and builds on a bachelor education in either electrical engineering or engineering physics/applied physics. During the first three semesters students study in three different universities and thereby get an exposure to different academic cultures in Europe. In the last semester the students can choose to do a master thesis project in as many as seven different institutions.
During my presentation I will present this master program in more detail and answer questions.
