Fiber raman amplifier
WebThe use of oxide glasses as dopants for fiber fabrication is suitable to enhance the Raman gain coefficient. For example, in the case of pure GeO 2, the Raman gain coefficient is about 9.2 times that for pure SiO 2 glass. In fact, doping the core of an SiO 2 Raman fiber amplifier with GeO 2 has two beneficial effects. First, the index difference Δ is raised, … WebIn fiber Raman amplifiers (FRAs), a power transfer from pump to information carrying the signal (usually described as a probe) can occur if there is a sufficient pump power within …
