Raman amplification /ˈrɑːmən/ is based on the stimulated Raman scattering (SRS) phenomenon, when a lower frequency 'signal' photon induces the inelastic scattering of a higher-frequency 'pump' photon in an optical medium in the nonlinear regime. As a result of this, another 'signal' photon is produced, with the surplus energy resonantly passed to the vibrational states of the medium. This process, as with other stimulated emission processes, allows all-optical amplification. Optical fiber is … Webb20 nov. 2024 · Abstract. An accurate design for a Photonic Crystal fiber (PCF) Raman amplifier has been developed. In this PCF, the geometric parameters, Raman gain coefficient, effective mode area, the Germania concentration in the doped area, and dispersion and confinement loss characteristics have been investigated at 1.55 μm.
