Course Contents:
The lecture discusses the working principle of the most important devices and components of modern telecommunication networks and optical data transmission systems. The starting point will be basic physical principles:
The nature of light
- Wave equation
- Polarization
- Absorption, transmission, reflection, refraction
- Mirrors, HR-/AR coatings
Waveguides
- Fiber-optic waveguides
- Attenuation, modes, dispersion
- Fiber types
- Connectors and splices
- Dispersion and dispersion compensation
- Kerr nonlinearity and self-phase modulation
Components, e.g.:
- Optical filters
- Wavelength division multiplexers
- Magneto-optical effect / optical isolator / circulator
- Electro-optic modulator
Lasers
- Basics, concepts, types
- Erbium-doped fiber lasers / amplifiers (EDFL / EDFA)
- Optical semiconductor laser / amplifier (laser diode)
Modulation
- Amplitude-, phasemodulation, QPSK
- Hardware for modulators
- Physical limits and constraints on communication channels
Other selected components and devices
