We demonstrate experimentally that a wide control of the group velocity of light can be achieved in conventional optical fibers by use of the stimulated Brillouin scattering effect.

Une fibre optique est un fil dont l’âme, très fine et faite de verre ou de plastique, a la propriété de conduire la lumière et sert pour la fibroscopie, l'éclairage ou la transmission de données numériques. Elle offre un débit d'information nettement supérieur à celui des câbles coaxiaux et peut servir de support à un réseau « large bande » par lequel transitent aussi bien la télévision, le téléphone, la visioconférence ou les données informatiques.
Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 100 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. The standard G.651.1 defines the most widely used forms of multi-mode optical fiber.
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for optical communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building.
