Abstract

We experimentally show that, when stimulated Brillouin scattering is generated in optical fiber by use of monochromatic cw pump radiation, the transmitted pump radiation exhibits spectral broadening that is much narrower than the classical homogeneous gain-narrowed Brillouin bandwidth. The bandwidth is practically independent of the pump strength, fiber characteristics, and the waveguide-induced inhomogeneously broadened bandwidth of the Stokes emission. We show that these properties arise from strong parametric coupling of the Stokes and pump signals in the pump-depletion region.

a, d, Time recordings and b, c, e, f, rf spectra of a–c, TPR and d–f, Stokes emission for normalized incident pump power N=1.5. Spectra b and e are taken for a single-mode fiber with a NA of 0.24, L=200 m, and dc=3 µm, and spectra c and f are for a two-mode fiber with a NA of 0.12, L=650 m, and dc=9 µm. The scale for the spectra is the same as that for Fig. 2.

Ia–Ic and IId–IIf, Measured and I and II, calculated spectra of TPR. I and I are for the same N=2 with various values of L: a, 100; b, 650; and c, 3600 m. II and II are for the same L=650 m with various values for N of d, 2; e, 4; and f, 10. The scales for the experimental spectra are the same as shown in II; they are logarithmic (relative units) in the vertical and linear (in MHz) in the horizontal directions.
