Active Optoelectronic Devices (AOD)
This module focuses on advanced topics in semiconductor laser diodes, photodetectors, and optical modulators, predominantly for use in high-speed optical communication systems. Depending on the vote of the audience, the lecture is given in either German or English.
- Edge-emitting semiconductor lasers: longitudinal multimode, lateral and transverse mode behavior, temperature effects, optical near- and far-fields, frequency modulation, mirror coatings, laser noise, high-power lasers, DBR and DFB lasers for use in telecommunications, tunable laser diodes
- Vertical-cavity surface-emitting lasers (VCSELs): principles and applications
- Photodetectors: PIN-type, avalanche photodiode (APD), metal–semiconductor–metal (MSM), resonant-cavity-enhanced, waveguide-type, high-speed designs
- Optical modulators: physical effects (plasma, electroabsorption (Franz–Keldysh), quantum-confined Stark (QCSE), electro-optic (Pockels)), phase modulators, Mach–Zehnder interferometer (MZI) modulators, absorption modulators, generation of higher-order modulation formats such as quaternary phase shift keying (QPSK) or quadrature amplitude modulation (QAM) used in modern optical communication systems
- A comprehensive English written manuscript is provided.

- Bachelor degree
- Modules Einführung in die Optoelektronik or Optical Communications
- Until the summer semester 2019 this modules was called Optoelectronic Devices (OD).
- Adding one hour of exercises per week in 2020 required a new name, which is now AOD.
