SK2811 Fiber-optical Communication 7.5 credits

Fiberoptisk kommunikation

The high ways of the IT society are the optical fibers. An optical fiber can transport several tens of terabit per second over hundreds of kilometers. Fiber-optic communication is an established technique but is simultaneously in rapid technical development towards higher bit-rates and more complex networks. The course will give you the knowledge in order to understand both the fundamentals and the rapid development, that you as professional engineer can use the fiber optics efficiently. The course treats important devices as optical fibers, laser diodes, optical detectors, and receivers from physical and transmission system point of view. You will also learn how to optimise optical communication links and calculate the bit error rate. The language is english

Intended learning outcomes

The course content is knowledge of fibre optical components, links, and systems. The system relevant parameters of devices are derived from a physical description, and these parameters form the basis for designing fibre optic links.

After a completed course the participants should be able to:

  • Understand, describe, analyze, compare the most important devices: light sources, fibres and detectors from both physical and system point of view.
  • Design digital fibre optic links and.

Course main content

Dielectric wave-guides: Attenuation, wavelength dispersion.

Light sources: Semiconductor laser, light emitting diode, rate equations, output power, modulation, noise, laser amplifiers, chirp.

Detectors: PIN diode, avalanche diode, responsivity, bandwidth, noise,

Systems: Direct detection systems, heterodyne systems, attenuation limitations, dispersion limitations, signal dependent noise, additive noise, bit error rate, optical networks, solitones.

Eligibility

Bachelor's degree in physics, electrical engineering or equivalent degree

Recommended prerequisites

It is anticipated that the students are acquainted with:
- Waveguides: Wave equation and the concept of modes. 
- Solid-state electronics: p-n-junction
- Circuit theory: Impulse response, convolution, transfer function of linear systems.
- Signal theory: Auto correlation function, power spectral density
