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...
متن کاملThermal Effects Study on Stimulated Brillouin Light Scattering in Photonic Crystal Fiber
we investigate the temperature-dependences of the Brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. Positive dependences coefficients of 0.77, 0.56 and 1.45MHz/0C are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. The results indic...
متن کاملCHARACTERIZATION OF STIMULATED BRILLOUIN SCATTERING AND Bi-EDFA AS A CONVENTIONAL BRILLOUIN FIBER LASER
Stimulated Brillouin Scattering (SBS) is one of the nonlinear process that can occur in optical fiber if the input power at low level [1,2]. It is a natural scattering process associate to the propagation of light in a medium. Due to the interaction of light with the propagation medium, different scattering components are generated: Rayleigh, Brillouin and Raman component. The resulting scatter...
متن کاملAnalysis of Steady-State Brillouin Nonlinearity in High-Power Fiber Lasers
In the present work, a theoretical analysis of the first-order of stimulatedBrillouin scattering (SBS) in a double-clad (DC) ytterbium (Yb)-doped silica fiber laserin unidirectional pumping mode is presented.An accurate simulation for calculating SBS nonlinearity is performed by considering thecoupled differential rate equations for pump, signal and Stokes powers, as wel...
متن کاملEntanglement in the Process of Stimulated Brillouin Scattering of Light
Spontaneous Brillouin scattering which is considered to be a scattering of light at the acoustic waves caused by thermal fluctuations was investigated in 1922. Physically stimulated Brillouin scattering (SBS) is analogous to another type of stimulated scattering of light stimulated Raman scattering (SRS) of light in which the laser light is scattered by the vibrational mode of the medium. The m...
