Prerequisiti
Basic knowledge of electromagnetic theory, optics and electronics from the courses of the First Level Degree in Electronics and Telecommunications; basic knowledge on lasers and photodetectors.
Obiettivi formativi
This course is a survey on optical communications, and provides information on the propagation medium (the fiber), lasers and detectors, passive components,optical amplification, and telecommunication systems.
Programma e contenuti
Optical Fiber, Emitters and Photodetectors, Passive components, Networks, Measurements

Optical Fibers
Single-mode and multi-mode fibers, specialty fibers. Geometrical and optical parameters. Modal theory of fibers. Attenuation. Dispersion.

Emitters and Photodetcters
Lasers and LEDs for optical communications. Laser/fiber coupling. Photodiodes for optical communications.

Passive components
Connectors and splices. Coupled-mode theory. Couplers; mirrors and resonators with couplers. Retarders and polarizer. Isolators and circulators. Modulators. Bragg gratings and filters. Arrayed waveguide devices.

Telecommunication systems
Point to point interconnections. Networks. Power budget. Electro-optic repeater. Optical amplifiers. Multi-wawelength transmission (WDM). Coherent detection.

Measurements

Measurements on fibers and on devices for optical communications: power, attenuation, return loss, geometrical parameters, dispersion and frequency response. OTDR, BER tester.
Metodi didattici
The course includes frontal lessons, during which the course topics are carried out including several examples, using overhead projection of transparencies and Powepoint presentations. The course is completed by some laboratory activity, where optical devices and measurement instrumentation for optical networks are shown.
