Paper Abstract

In this paper the SRS characteristic of a phosphorus-doped fiber made for RFLs is experimentally investigated. At an averaged pump power of 0.5W we observe three spectral lines in the output spectrum, which correspond to the first order Stokes of silica at 1.12μm, the third order Stokes of silica or the first order Stokes of P2O5 at 1.24μm, and the fourth order Stokes of silica at 1.31μm, respectively. When the pump power is increased to the maximum value of 2W, there in the spectrum appears a continuum near 1.54μm with a FWHM of more than 50nm. The expected fifth Stokes of silica at 1.39μm and the second Stokes of P2O5 at 1.48μm are not observed. We demonstrate that the fiber loss in the region of 1-1.5μm plays an important role in the development of SRS in phosphorus-doped fibers.
