Stimulated Raman scattering in soft glass fluoride fibers

Investigation 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...

Cross-phase modulation and induced focusing due to optical nonlinearities in optical fibers and bulk materials

Cross-phase modulation (XPM) and induced focusing occur when copropagating ultrafast pulses interact in a nonlinear medium. XPM and induced focusing are investigated as new techniques to control the spectral, temporal, and spatial properties of ultrafast pulses with femtosecond time response. In this paper we review our most recent measurements on (1) induced spectral broadening in BK7 glass, (...

Comprehensive Theoretical Study on Threshold Power of Stimulated Brillouin Scattering in Single-Mode Fibers

We have investigated and developed a theoretical approach to explore stimulated Brillouin scattering (SBS) phenomena in single mode fiber. SBS happening threshold power condition has been studied in terms of fiber parameters and input pump power. To assess threshold power precisely, the pump depletion effect and fiber loss has been included by employing 1% criterion. The threshold exponential g...

Femtosecond Laser Amplification Based on Stimulated Raman Scattering in Optical Fibers

Self-phase modulation and optical pulse compression influenced by stimulated Raman scattering in fibers

We have investigated experimentally the influence of stimulated Raman scattering, under conditions of pulse walkoff, on the propagation of mode-locked 1.06-,um pulses in single-mode, polarization-preserving fibers and on their subsequent pulse compression. Intense stimulated Raman scattering preferentially depletes (and steepens) the leading edge of 1.0 -,4m pump pulses and clamps the pump puls...
