Abstract(in English) | We demonstrate depolarization of pump LD to diminish PDG in Raman amplifiers in order to decrease the number of LDs. By optimizing pump wavelengths and using depolarized LD, we realize cost-effective pumping unit comprising only two LDs, to obtain a sufficiently flat Raman gain over the conventional EDFA gain band (C-band:1530-1560nm). As an example of the application, EDFA gain tilt is controlled by means of Raman gain in DCF instead of a variable optical attenuator in an in-line amplifier, so that the gain flatness and output power can be simultaneously maintained constant against input power variation. |
