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

Content and learning outcomes
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.
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.
Literature and preparations
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
Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
- LAB1 - Laboratory work, 1.5 credits, grading scale: P, F
- TEN1 - Exam, 6.0 credits, grading scale: A, B, C, D, E, FX, F
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.
Other requirements for final grade
One written examination (TEN1, 6 credits) and lab course (LAB1, 1.5 credit)
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
