Low-Frequency Vibrational Excitations in a Niobium-Phosphate Glass for Raman Gain Applications
Raman gain for all-optical amplification depends significantly on the cross section for spontaneous Raman scattering. We present measurements of the Raman spectrum of binary niobium-phosphate glasses in the frequency range from 5 – 1300 cm. The spectra of these glasses show a low-frequency enhancement of the vibrational density of states (‘Boson peak’) suggesting a significant gain profile for ...
متن کاملInelastic light , neutron , and X - ray scatterings related to the heterogeneous elasticity of glasses
The effects of plasticization of poly(methyl methacrylate) glass on the boson peaks observed by Raman and neutron scattering are compared. In plasti-cized glass the cohesion heterogeneities are responsible for the neutron boson peak and partially for the Raman one, which is enhanced by the composition heterogeneities. Because the composition heterogeneities have a size similar to that of the co...
متن کاملInvestigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers
In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...
متن کاملVibrations and Diffusion of Atoms in Superionic Crystals and Melts
Recent computer simulation studies contain sufficient information about the atomic disorder and motion to allow a calctlation of the dynamical response of superionic crystals and melts which may be compared with measurements of inelastic neutron scattering and Raman scattering. The high frequency part of this response is essentially that of anharmonic vibrations in a disorderd lattice. The low ...
متن کاملObservation of Raman Gain in Reduced Length of Bismuth Erbium Doped Fiber
Raman amplification of a 49 cm Bismuth oxide (Bi2O3) as a nonlinear gainmedium based erbium doped fiber amplifier (EDFA) is reported in new and compactdesign in near infrared spectral regions. The bismuth glass host provides theopportunity to be doped heavily with erbium ions to allow a compact optical gain fiberamplifier design by using reduced fiber length and the 1480...
