FSK3883 Fiber-Optic Communication 9.0 credits

Dielectric waveguides: Attenuation, wavelength dispersion, modes, fields.
Light sources and optical amplifiers: Semiconductor laser, light-emitting diode, rate equations, output power, modulation response, chirp, noise, optical amplifiers.
Detectors: PIN-diode, avalanche diode, responsivity, bandwidth, noise.
Transmission systems: Optical links, direct detection systems, soliton systems, coherent systems, multilevel signaling, dispersion limitations, attenuation limitations, additive noise, signal dependent noise, bit error rate, optical networks, simulation and design

Knowledge of fiber-optical components and systems with applications to communications. Parameters of devices that are relevant for the system performance are derived from physical descriptions, and form the input parameters for the design of fiber-optic links.
After a completed course, the participants should be able to:

• understand, describe, analyse, and compare the most important devices: optical transmitters, optical fibers, and optical detectors
• design digital fiber-optic links.
• simulate a multilevel coherent fiber-optic communication system using computer software

Enrolled as PhD student.
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

• TEN1 - Written exam, 6.0 credits, grading scale: P, F
• PRO1 - Project work, 1.5 credits, grading scale: P, F
• LAB1 - Laboratory work, 1.5 credits, grading scale: P, 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.

If the course is discontinued, students may request to be examined during the following two academic years.

TEN1: written exam, 6 hp, grading: P/F
 Calculator, mathematic handbook, the course book and the lecture notes (but NOT exercise notes) are allowed and recommended aids
LAB1: laborations,  1.5 hp, grading: P/F
PRO1: projekt task,  1.5 hp, grading: P/F

To pass the course the student should pass the written exam, the lab exercises and the project assignment.
