Knowledge
This course, which is composed of two parts, after providing the necessary fundamentals on optical components, will overview the most commonly used optical amplification and optical fiber sensor technologies. The course will also provide a hands-on laboratory module, where students will learn how to work and carry out experiments with optical amplifiers and components
Optical amplification has been one of the most important enabling technologies in communications during last years, which has allowed for the extraordinary increase in capacity and transmission distance underlying the present worldwide development of Internet and network-based services.
