Advanced Optoelectronic Communication Systems - Devices and Applications
This lecture provides an advanced overview over modern optical telecommunication and datacom systems as well as associated optoelectronic devices which form the backbone of the so-called Tera-Era, referring to the Terabits per second flowing through today's optical fiber strands. Students will be able to understand the operation principles, potentials as well as limitations of various technologies.
The lecture thus serves as a foundation upon which practical or theoretical research work in the Institute of Optoelectronics or later employment in the industry can be built.
The following topics are addressed:
- Introduction to optical communication systems
- Multiplexing techniques and high-capacity DWDM systems
- The CWDM approach
- Single-mode fiber types
- Fiber dispersion limitations and dispersion management
- Polarization mode dispersion
- Nonlinear fiber transmission effects
- Optical amplifiers: EDFA and Raman amplifier
- Fiber Bragg gratings
- Devices for optical multiplexing and demultiplexing
- Planar lightwave circuits
- Optical MEMS
- Advanced semiconductor lasers for use in telecommunications:
DBR and DFB lasers
- Laser-modulator integrated DWDM sources
- High-power lasers and associated problems
- Vertical-cavity surface-emitting lasers for datacom applications
- Photodetectors: Schottky, MSM, avalanche, and resonant cavity enhanced PDs
Depending on the vote of the audience, the lecture is given either
in German or English.
Literature: A comprehensive English written manuscript is provided.
