Abstract

The magnitude of the stimulated Raman gain spectrum will depend on the absolute pump wavelength. Measurements of the pump-wavelength scaling of the stimulated Raman gain of several single-mode fibers are presented. The measurements were obtained by use of two techniques: a brute-force comparison of gain versus pump wavelength and a more elegant comparison of the asymmetry in the Stokes and anti-Stokes Raman gain spectrum at a fixed pump wavelength. This second asymmetry technique has the advantage that it is independent of the uncertainties typically associated with relative measurements of optical power.

Raman gain gRM spectra versus frequency offset Δω/2π for LEAF fiber at increasing pump wavelengths of (solid curve) 1460 nm, (dotted curve) 1500 nm, (short-dashed curve) 1540 nm, and (long-dashed curve) 1580 nm. Also plotted is the asymmetry A in the Raman gain spectrum for the 1500-nm data. The linear fit is almost obscured by the data points.
