Abstract

DCF optical fiber Stokes Raman forwrad scattering and backward scattering gain spectrum have been measured by Raman laser as a pump source and high spectral resolution four grating spectrometer. There are 15 phonon modes in the Stokes forward scattering region and 18 phonon modes in the Stokes backward scattering region. In the low frequency region, there are 3 characteristic phonon modes they are 41.4 cm^-1, 68.0 cm^-1 and 96.7 cm^-1. The characteristic Raman peaks of DCF fiber is 434.7 cm^-1 and 455.4 cm^-1 that are correspond to 440 cm^-1 and 490 cm of normal single mode fiber as a function of pump power has been measured. Measured DCF Raman gain spectrum is different from that in common reference and books. The reasons are the high Ge0₂ concentration in DCF fiber and the developing of measuring technology.
