| Contents |
- Diffractive elements: 1-, 2- and 3-dimensional
gratings, Fresnel lenses and
photonic crystals
- Lasers: gain, rate equations, DFB gratings, spectra,
ultrafast lasers, tunable lasers,
chirped gratings, microdisc lasers, quantum cascade lasers, DBR mirrors
for
vertical cavity lasers, VCSELs, blue semiconductor lasers
- Light processing: switches, splitters, amplifiers,
combiners, multiplexers,
demultiplexers, beam transformers
- Optical communication systems: WDM, TDM
- Experimental modules such as DFB laser diodes, sample
stages, optical spectrum
analyzers and PC will be assembled to measure laser spectra as a
function of
injection current and temperature
- Measured are: spectral shift of different modes of
diode lasers with varying injection
current and temperature, light power-versus-current characteristics, T0
- Evaluation,
interpretation, documentation and presentation of the measured data
- Advanced seminar topics in
optoelectronics.

| Objectives |
- To learn basic principles of optoelectronic devices
and systems, structure and
operating principles of optoelectronic components
- To learn the huge application potential of
optoelectronic devices and photonic tools
- The engineer should learn to solve problems using
interdisciplinary analogies
- To understand the successful solutions of nature as a
promising approach for an
advanced working engineer
- To learn presentation techniques and to obtain
presentation practice
- To learn to structure a talk to optimize the transfer
of essentials to the audience
- Introduction to scientific working. The engineer
learns how to analyze measured
data and how to compare experimental and theoretical results and
inferences
- To learn to efficiently apply different set-up
components for optical characterization.
