Hello, dear first semester students!

2
00:00:06.600 --> 00:00:12.000
My name is Andreas Stöhr. I am a professor at the University of Duisburg-Essen and head the Department of Optoelectronics

3
00:00:12.100 --> 00:00:27.000
I'm delighted to welcome you to the university and that you have decided to study here in Duisburg. I will now introduce you to our teaching and research activities in the Department of Optoelectronics.

4
00:00:27.100 --> 00:00:32.500
What are your teaching activities?

5
00:00:32.600 --> 00:00:43.500
We have numerous courses: in the Bachelor's programmes, we will see each other for the first time in higher semesters for the lecture "Optoelectronics".

6
00:00:43.600 --> 00:00:52.000
You will learn about the interaction between light and matter and understand how lasers, light-emitting diodes and other optoelectronic components work.

7
00:00:52.100 --> 00:01:03.000
In advanced semesters - if you are also doing your Master's at this university - we will see each other at courses like "Optical Networks", "Integrated Photonics" or "Laser Technology".

8
00:01:04.100 --> 00:01:09.500
Hello, dear first semester students! My name is Rüdiger Buß and I am the second lecturer at the Department of Optoelectronics.

9
00:01:09.600 --> 00:01:21.000
We will meet each other during the "EIT First Semester Workshop" in case you are studying Electrical Engineering, in the "Medical Engineering Lab" if you are studying Medical Engineering,

10
00:01:21.100 --> 00:01:30.500
or during "Optical Communications Technology" if you are enrolled in other degree programmes such as Nanoengineering, Embedded Systems Engineering or Industrial Engineering and Management.

11
00:01:30.600 --> 00:01:36.500
Later in the Master's programme you can attend my course "Optical Signal Processing".

12
00:01:36.600 --> 00:01:42.000
Well, in any case, I'm delighted that you're taking part and: "Welcome aboard!"

13
00:01:42.100 --> 00:01:45.500
What are your research activities?

14
00:01:46.600 --> 00:01:54.000
The Department of Optoelectronics is located at the Centre for Semiconductor Technology and Optoelectronics, which you can see here in the background.

15
00:01:54.100 --> 00:02:03.000
We operate a 500 square metre clean room together with colleagues from the department "Components of High Frequency Electronics"

16
00:02:03.100 --> 00:02:18.000
At this point, I may say that this is an exceptional situation in Germany. Our infrastructure is really outstandingly good. We are therefore also integrated in numerous national and international (research) activities.

17
00:02:18.100 --> 00:02:34.000
I can say that we are involved with colleagues in the DFG's Transregional Collaborative Research Centre TRR 196 (MARIE). Overall, there are very few TRRs in the field of electrical engineering (Germany-wide).

18
00:02:34.100 --> 00:02:48.500
We are part of the BMBF's High-Tech Initiative and are also working on a Terahertz Integration Centre, funded by the EU.

19
00:02:48.600 --> 00:02:55.500
We are also coordinators in a European graduate school dealing with terahertz photonics.

20
00:02:55.600 --> 00:03:07.100
For all this work, we use the clean room that you see in the background. This is where we develop integrated photonic chips.

21
00:03:07.600 --> 00:03:14.000
You can think of it like it was in microelectronics at the time when ICs were developed. A lot of transistors were integrated at that time.

22
00:03:14.100 --> 00:03:26.000
We are integrating optical components instead. It is possible to generate light, to store light, and to modulate it; this is what we do here in integrated photonics.

23
00:03:27.100 --> 00:03:30.500
Where is the link between your research and teaching?

24
00:03:30.600 --> 00:03:45.500
Our teaching activities - and thus our range of courses - naturally also reflect our research to some extent. Thus, you will find research topics that we are working on in class.

25
00:03:45.600 --> 00:03:55.000
If I may mention "Integrated Photonics" as an example, where we are discussing issues such as the integration of different optical functionalities on one chip.

26
00:03:55.100 --> 00:04:06.000
We also offer a lecture on "Optical Networks", where we are discussing questions like "How does our Internet work?", "How is such an optical communication system actually to be understood?", "How does it work?".

27
00:04:06.100 --> 00:04:18.000
In addition, we offer the lecture "Laser Technology", in which you will understand what different types of lasers are available and how the most common types among them work.

28
00:04:19.000 --> 00:04:36.000
One more point I would like to mention: You can work as a student assistant at our institute parallel to your courses. And we would be pleased if you are interested. If so, you will be involved in the research work of the corresponding doctoral students who are working at the institute.

29
00:04:36.500 --> 00:04:47.000
You are welcome to carry out your project thesis or even your final thesis at our institute: These are bachelor's theses or - for some of you - also later the master's thesis.

30
00:04:47.100 --> 00:04:50.000
We are looking forward to seeing you!
