Abstract

A pump source for a fiber Raman amplifier is formed to include a polarization scrambler to reduce the effects of polarization dependent gain, particularly as used in a multiple input wavelength WDM optical system. The source utilizes a polarization scrambler coupled to the output of a pump laser, the scrambler controlled by a sinusoidal input signal to impart a randomness to the polarization of the pump signal. Thus, a random state of polarization of the pump signal, with respect to the various input signal wavelengths, improves the overall gain experienced by the system.
