| Abstract(in English) | To realize low PDG (polarization dependence of gain) Raman amplification, a simple depolarization method for pump light is studied. Optical spectrum of Fabry-Perot semiconductor laser diode is modeled with regard to both line width and frequency spacing of longitudinal modes, and calculated degree of polarization (DOP) is consistent with measured value. As a result, pump light is well depolarized and Raman PDG could be suppressed with PMF (polarization maintaining fiber) which is not long enough to depolarize each longitudinal mode, if PMD of PMF is properly designed and avoid neighborhood of reciprocal number of frequency spacing of longitudinal modes. This method enables simple configuration of low PDG Raman amplifiers. |
