All-fibre devices for modern telecommunication systems

摘要

Optical fibre technology enables the implementation of several key operations that increase the functionality of the optical layer in modern communication networks. Thus, optical fibres are used not only for transferring data signals from one point to the next, but also to implement sophisticated devices such as filters, amplifiers, or even ultrafast all-optical switches. This talk will review some of the most enabling fibre-based devices, such as the erbium-doped fibre amplifier and the fibre Bragg grating, and will also explore the exploitation of fibre nonlinearities for the implementation of switching devices.
