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...
Figure 4.13 shows this Raman coefficient CR (=g/Aeff) as a function of the frequency shift in the case of NZDSF, SMF, and RDF fibers, where g is the Raman gain coefficient (spontaneous emission or stimulated emission spectrum for the Stokes process) and Aeff the effective area of the ...
Two kinds of Nb-doped silica fibers, an NbCl5-doped fiber and an Nb2O5-doped fiber, are fabricated and characterized in this Letter. First, the refractive index profiles of both fibers are obtained, and then their Raman spectra are measured with 785 nm exciting light. The Nb-doped fibers...
S2c). Briefly, self-phase modulation can induce self-balanced spectral splitting of picosecond Stokes beam propagating in standard single-mode silica fibers, resulting in two required wavelength-shifted Stokes beams. Second, SREF signal shall better be detected by single-photon counters rather than ...
Investigation of Stimulate Raman Scattering Spectrum in Silica Optic Fibers 来自 知网 喜欢 0 阅读量: 23 作者:X Zhao,X Jia,B Jin 摘要: According to characteristic of the Raman gain curve, the Raman spectral region of interest was divided into a number of small frequency intervals.The Stocks ...
We demonstrate long-range enhancement of fluorescence and Raman scattering using a dense random array of Ag nanoislands (AgNIs) coated with column-structured silica (CSS) overlayer of over 100 nm thickness, namely, remote plasmonic-like enhancement (R

The Raman gain coefficient gr for typical silica fibers extends over a relatively large frequency range (e.g., up to 40 THz) with a broad peak centered at approximately 13.2 THz (this corresponds to 440 cm−1). The relatively large frequency range results from the amorphous nature of the...
