TECHNIQUE AND DEVICE FOR CONFORMING BRILLOUIN'S GAIN SPECTRUM ON OPTICAL WAVE GUIDES

Technique and device for shaping the gain spectrum of the brillouin effect in optical waveguides (hereafter guides). By injecting a luminous radiation or "pumping" in guides, another radiation can be induced -dispersion (scattering) of brillouin- centered on another frequency. This dispersion can be spontaneous or stimulated by another counter-propagating radiation ("seed") and amplified in the brillouin spectral gain band whose profile depends on the properties of the guide and of the pumping. This invention proposes the connection of n concatenated and/or star guides, all of which are pumped with the same pumping source (s) as a technique to form the brillouin spectral response of the set of guides that constitute the base device. It can be used in the development of optical devices and subsystems (optically tunable or not). It can be implemented in fiber optic technology and used for amplification, filtering, measuring and in general, processing of optical signals.
