TLDR
In this article, the stimulated Brillouin scattering (SBS) spectrum in an optical fiber is shown to be inhomogeneous, exhibiting spectral broadening and hole burning under cw monochromatic laser excitation.Abstract:
We report experimental results which show that the stimulated Brillouin scattering (SBS) spectrum in an optical fiber is inhomogeneous, exhibiting spectral broadening and hole burning under cw monochromatic laser excitation. This phenomenon arises from the waveguide interaction of the pump and Stokes signals and is a fundamental property of SBS in waveguiding systems due to their ability to confine a fan of radiation wave vector directions.read more

Waveguide-induced inhomogeneous spectral broadening of stimulated Brillouin scattering in optical fiber
TL;DR: It is shown that the SBS spectral width and gain depend on the numerical aperture for both single-mode and multimode fibers, the functional dependencies of which are in good agreement with the model description of the phenomenon.

Statistical properties of stimulated Brillouin scattering in single-mode optical fibers above threshold.
TL;DR: Numerical simulations are performed to obtain statistical and spectral characteristics of stimulated Brillouin scattering initiated by Gaussian noise in single-mode optical fibers and reveal how the probability function of Stokes power, the power-correlation function, and the SBS spectra evolve as key parameters of the model vary, leading to a modification of Stoke field statistics.

Threshold for stimulated Brillouin scattering in optical fiber.
TL;DR: Results of the calculations are in reasonably good correspondence with proper measurements in silica fibres, which have found in the literature and have done ourselves in fibre-samples without and with cavity feedback.

Evaluation methods and requirements for the stimulated Brillouin scattering threshold in a single-mode fiber
TL;DR: In this paper, the SBS threshold is evaluated by considering a 4% level change in the reflected power against the input power in terms of harmonization with the carrier-to-noise ratio (CNR).

Frequency domain aperture for the gain bandwidth reduction of stimulated Brillouin scattering
TL;DR: A novel method based on the inhomogeneous Brillouin gain saturation to reduce the gain bandwidth significantly below its natural value is proposed.
