Algemene competenties

AIMS:

The primary learning objective is to acquire a thorough understanding of laser diodes and to make the students acquainted with the dynamical behaviour of laser diodes (semiconductor lasers). After the course, students should be able to follow the literature in this field and/or do research themselves.

This course is part of the programme of the Interuniversitary Master in Photonics since 2007.

 

COMPETENCES:

Being able to use the rate equations for the derivation of large and small signal dynamic behaviour. Being able to simulate the behavior of lasers diodes based based on rate equations.

Being able to derive the different noise characteristics from the rate equations.

Understanding the different methods for the generation of short laser pulses.

Understanding the influence of external reflections on laser diode behaviour.

Being able to apply the basic concepts of non-linear dynamics to laser dynamics.

Understanding the different approaches to obtain all-optical switching.

Acquire sufficient knowledge to perform research in the domain of laser dynamics

 

This course also contributes to the following competences:

- Knowledge-oriented competence:

Master and apply advanced knowledge in the own field of engineering in case of complex problems.

Apply Computer Aided Engineering (CAE) tools and sophisticated calculation- and communication-instruments in a creative and target-oriented way.

Be acquainted with the recent innovation trends in the domain of photonics, more particularly concerning recent trends in high speed dynamics of semiconductor lasers

Understand non-optical aspects of photonic systems, in particular electronic  and thermal aspects of semiconductor lasers.

 

- Scientific competence:

Perform research by means of scientific literature.

Understand the context of technical or scientific papers in the field of photonics and further investigate unclear parts independently.

 

- Intellectual competence:

Be aware of ongoing evolutions in the field of interest, improve competence to expert level.

 

- Competence in cooperation:

Report on technical or scientific subjects orally, in writing and in graphics.

 

- Societal competence:

Have an insight in the photonics industry and in the role of photonics in the scientific and technological evolution of society.

 

- Profession specific competence:

Master the complexity of technical systems by the use of system- and process models.

Dispose of enough knowledge and comprehension to control the results of complex calculations or make approximate estimates.

Use photonic components and systems accurately.

 

EXAM REQUEST:

The students are evaluated according to their knowledge of the different competences.
