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.

Course syllabus SK2811 (Spring 2022–)The course codefor phfdstudentsareSK3885.
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.
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:
English B / English 6
Bachelor's degree in physics, electrical engineering or equivalent degree
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
If the course is discontinued, students may request to be examined during the following two academic years.
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
One written examination (TEN1, 6 credits) and lab course (LAB1, 1.5 credit)
