摘要: The commonly used Lorentzian Raman response function does not properly account for the shoulder in the Raman gain spectrum originating from the Boson peak. We propose an accurate model for the Raman response in silica fibers.关键词:
The Raman gain spectrum has been measured for silica glasses as well as silica-based fibers [10–18]. Figure 9.3 shows the Raman gain coefficient for bulk silica as a function of the frequency shift Ω when the pump and signal are copolarized (solid curve) or orthogonally polarized (dotted...
