Stimulated raman scattering fiber
WebMar 11, 2011 · The Raman scattering reflects the resonances of a given material. In the case of optical fibers, they are basically made of fused silica, which is an amorphous material. If only the pump wave is launched into the fiber, the generation of the Stokes wave begins with spontaneous Raman scattering. Raman amplifiers offer some important … WebWe present the investigation of the onoff contrast in an optical switch - using stimulated Raman Scattering in optical fibers. The setup consists of a Raman circuit of two fiber stages connected in series with a spectral filter rejecting the signal inserted between them. The stage 1 works as saturated amplifier, p pulses are in this stage the pum
